Installing the Data Fabric Client on Ubuntu (Non-FIPS)

This section describes how to install the Data Fabric client on Ubuntu.

  1. Remove any previous data-fabric client software. You can use dpkg --list | grep mapr to get a list of installed data-fabric packages. Then type the packages separated by spaces after the dpkg -r command. For example:
    dpkg -r mapr-core mapr-fileserver

  2. Update your Ubuntu repositories. For example:

    apt-get update
  3. Import the package keys to enable signature verification:
    wget --user=<email> --password=<token> -O /tmp/maprgpg.key -q https://package.ezmeral.hpe.com/releases/pub/maprgpg.key && rpm --import /tmp/maprgpg.key
wget --user=<email> --password=<token> -O /tmp/hpeezdf.pub -q https://package.ezmeral.hpe.com/releases/pub/hpeezdf.pub && rpm --import /tmp/hpeezdf.pub && gpg --import /tmp/hpeezdf.pub
    Optionally, you may use commands to verify the signatures before installing the software. For more information, see HPE GPG Public Keys for GPG or RPM Signature Verification.
  4. Make sure the client is running JDK 11 or later:
    $ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home
$ /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/bin/java -version
openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

  5. Run the following command to install the data-fabric client:

    apt-get install mapr-client

  6. To use this client with a secure cluster or clusters, copy the ssl_truststore and ssl-client.xml files from the /opt/mapr/conf directory on the cluster to the /opt/mapr/conf directory on the client.

    If this client will connect to multiple clusters, you must merge the ssl_truststore files on the server by using the /opt/mapr/server/manageSSLKeys.sh tool, and then copy the merged file to /opt/mapr/conf on the client. For an example of merging the ssl_truststore files, see step 3 in Configuring Secure Clusters for Running Commands Remotely.

  7. Run configure.sh to configure the client. In the following examples:
    -N (uppercase) Specifies the cluster name
    -c (lowercase) Specifies a client configuration
    -secure Indicates that the cluster is secure
    -C (uppercase) Specifies the CLDB nodes
    -HS Specifies the HistoryServer node
    To ensure that the client can connect in the event of a CLDB node failure, all CLDB nodes are specified. For more information about the syntax, parameters, and behavior of configure.sh, see configure.sh.
    Secure cluster example
    /opt/mapr/server/configure.sh -N my.cluster.com -c -secure -C mynode01:7222,mynode02:7222,mynode03:7222 -HS mynode02
    Non-secure cluster example
    /opt/mapr/server/configure.sh -N my.cluster.com -c -C mynode01:7222,mynode02:7222,mynode03:7222 -HS mynode02
    NOTE

    If the cluster was configured with a cluster-admin user:group that is different from the default mapr:mapr value, you must include options to specify the cluster-admin user and group information when you run configure.sh to configure the client.

    If the cluster-admin user ID is present on the client node, include these options:
    • -u
    • -g
    If the cluster-admin user ID is not present on the client node, include these options:
    • -u
    • -g
    • --create-user | -a
    • -U
    • -G

  8. At the end of the client installation, run the maprlogin password command to create a valid ticket to connect to the cluster.
