- MFS-15570
- Using the Data Fabric client on Mac OS X fails with the following warning:
This warning is returned when you use the client to run the2023-01-17 10:13:51,170 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable fs/common/ossl_dynlib.cc:185: dlopen(libssl.1.1.dylib, 6): image not found
hadoop fs -ls
command.
- MFS-18249
- When you refresh the JWT access token and refresh token for a FUSE-based POSIX client manually, the FUSE-based POSIX client does not list the ticket, and remains in an inactive and dead state.
- MFS-18258
- When you add a new cluster to a cluster group, the FUSE-based POSIX client and the loopbacknfs POSIX client take about five mintues to load or list the newly added cluster.
Control System
For additional known issues related to the Control System, see the Control System Release Notes.
- DFUI-639
- A non-LDAP SSO user authenticating to Keycloak cannot create a volume, stream, or table using the Control System.
Database
- MAPRDB-2583
-
High File Server Memory Alarm is raised during replication of JSON tables that have row size less than 1 KB, and secondary indexes have been created on the JSON table being replicated.
- MFS-18188
- When you create a column in a table, the column name is prepended with "v." in the Column Permissions tab. When you create a new column, an additional "v." is prepended to the names of existing columns.
Data Fabric UI
Sign-in Issues
- DFUI-160
- If you sign in to the Data Fabric UI as an SSO user but you do not have fabric-level login permission, a sign-in page for the "Managed Control System" (MCS) is displayed. The "Managed Control System" sign-in is not usable for the consumption-based HPE Ezmeral Data Fabric.
- DFUI-437
- If you sign in to the Data Fabric UI as a non-SSO user and then sign out and try to sign in as an SSO user, a sign-in page for the "Managed Control System" (MCS) is displayed. The "Managed Control System" sign-in is not usable for the consumption-based HPE Ezmeral Data Fabric.
- DFUI-811
- If you launch the Data Fabric UI and then sign out and wait for 5-10 minutes and then attempt to sign in, a sign-in page for the "Managed Control System" (MCS) is displayed.
- DFUI-826
- In a cloud fabric, an empty page is displayed after a session expires and you
subsequently click on a fabric name. The browser can display the following
URL:
https://<hostname>:8443/oath/login
- DFUI-874
- Sometimes when you attempt to sign in to the Data Fabric UI, the "Managed Control System" (MCS) is displayed, or the Object Store UI is displayed.
- DFUI-897
- A user with no assigned role cannot sign in to the Data Fabric UI.
- DFUI-902
- Incorrect resource data is displayed when an LDAP user signs in to the Data Fabric UI without any SSO roles.
- DFUI-1123
- Attempting to sign in to the Data Fabric UI as a group
results in a login error message in the browser. For
example:
https://<hostname>:8443/login?error
- DFUI-1135
- The Data Fabric UI does not allow an SSO user to log in after an unsuccessful login attempt.
Mirroring Issues
- DFUI-1227
- If you create a mirror volume with a security policy, an error is generated when you try to remove the security policy.
- DFUI-1229
- Data aces on a mirror volume cannot be edited.
Display Issues
- DFUI-1186
- After you complete the SSO setup for a new fabric, fabric resources such as volumes and mirrors are not immediately displayed in the Data Fabric UI.
- DFUI-1221
- If a fabric includes a large number of resources, loading the resources to display in the Resources card on the home page can take a long time.
- MFS-18188
- When you create a column in a table, the column name is prepended with "v." in the Column Permissions tab. When you create a new column, an additional "v." is prepended to the names of existing columns.
- DFUI-2127
- When you set the access control of a table to Public, the Column families and Replication tabs do not display the create or edit options for your tables and table replicas.
- DFUI-1793
- When you set the access control of a column or column family to Public, the Name field is enabled.
- DFUI-2102
- When you create a table replica on a primary cluster with the source table on a
secondary cluster, the replication operation times out. However, the table replica is
successfully created on the primary cluster. The table replica appears in the
Replication tab, but does not appear in the Data Fabric UI
Graph or Table view for the primary
cluster.
This behavior is the same for both a source table on the primary cluster and the replica on the secondary cluster.
- DFUI-2175
- The Client library side drawer displays the same export environment variable for both the access token and refresh token.
- DFUI-2099
- When you delete a table replica from the Data Fabric UI Home page, the table replica remains listed in the Replication tab. When you select the table on the Replication tab, a message returns stating that the requested file does not exist.
- DFUI-2128
-
For external S3 buckets, the size of individual buckets is displayed as zero on the Resources card, even when the individual buckets contain one or more objects.
- DFUI-2136
-
The Overview tab for an external S3 bucket does not display any bucket-related information.
- DFUI-2095
- Security policy created on global policy master immediately before creating a volume
on secondary fabric is not available to assign to the volume, while creating the
volume.
Workaround: Wait for about 15 minutes and then create the volume to which you wish to assign the new security policy.
- DFUI-2161
-
When a node has multiple IP addresses (for example, the node has both IPv4 and IPv6 addresses associated with it), the IP addresses are missing a comma or a space, or any other separator between the individual IP addresses, on node access point modal.
External S3
- DFUI-2157
- Editing buckets on external S3 servers is not supported.
Installation
See also Installer Known Issues.
- DFUI-565, EZINDFAAS-169
- Installation or fabric creation can fail if a proxy is used for internet traffic with the HPE Ezmeral Data Fabric.
- DFUI-1224
- Under Administration, in the Fabrics card, the Data Fabric UI can show the progress of installation as 100% and the status as Inactive before certain post-installation activities are complete.
NFS
- MFS-16516
- When more than one external NFS servers in a cluster group are mounted on the
/mapr
path, and at least one external NFS server is inactive, thels /mapr
command hangs at the command prompt.
NFSv4
- MFS-18264
- Attempts to mount the NFSv4 server fail and return the following
error:
Mount.nfs4: Stale file handle
Object Store
- MFS-17233
- On cloud (AWS, Azure, or GCP) fabrics, if an instance is rebooted, the public IP addresses can change. If this happens, the MOSS certificates must be regenerated to include the new IP addresses, and the changes must be propagated to all fabric nodes.
- DFUI-519
- An SSO user is unable to create buckets on the Data Fabric UI and the Object Store. This is applicable to an SSO user with any role such as infrastructure administrator, fabric manager or developer.
- DFUI-577
- Downloading a large file (1 GB or larger) can fail with the following
error:
Unable to download file "<filename>": Request failed with status code 500
- DFUI-623
- Non-LDAP SSO user authenticating to Keycloak is unable to log on to the Object Store UI.
- MFS-16362
- When one or more tags have been assigned to an object, it is not possible to remove all tags while editing the object via the Object Store UI.
Online Help
- DFUI-459
- If a proxy is used for internet traffic with the HPE Ezmeral Data Fabric, online help screens can time out or fail to fetch help content.
Security Policies
- DFUI-2106
- A newly created policy cannot be assigned immediately to a fabric resource such as a volume on a secondary fabric in the global namespace.
- MFS-18154
- A security policy created on a cloud-based primary fabric (such as AWS) is not replicated on to a secondary fabric created on another cloud provider (such as GCP).
Topics
- DFUI-637
- Non-LDAP SSO user authenticating to Keycloak cannot create topic on the Data Fabric UI.
- DFUI-639
- A non-LDAP SSO user authenticating to Keycloak cannot create a volume or stream using the Data Fabric UI.
Upgrade
- EZINDFAAS-581
- Because of a known issue (EZINDFAAS-581), upgrades of cloud fabrics from release
7.4.0 to 7.5.0 can fail because the
keypair.pem
file has the wrong permissions. This issue affects upgrades on AWS, Azure, and GCP, but does NOT affect upgrades for on-premises fabrics.
- MFS-18222
- Suppose you use the seed node deployment steps to create a fabric
(
f1
), and then you add a fabric (f2
). If you then upgradef1
successfully as fabric manager, and then you sign in tof1
and initiate an upgrade off2
, the upgrade off2
might fail because of a state mismatch.
- OTSDB-147
- After upgrading OpenTSDB from version 2.4.0 to version 2.4.1, the Crontab on each OpenTSDB node is not updated and continues to point to the previous OpenTSDB version.
- COMSECURE-615
- Upgrading directly from release 6.1.x to release 7.x.x can fail because the upgrade
process reads password information from the default Hadoop
ssl-server.xml
andssl-client.xml
files rather than the original.xml
files. Note that upgrades from release 6.2.0 to 7.x.x are not affected by this issue.
Volumes
- DFUI-638
- Non-LDAP SSO user authenticating to Keycloak cannot create volume on the Data Fabric UI.
Workaround: Create a volume via the Data Fabric minIO client.
