Step 5: Verify Installation Success
To confirm success, check each node.
To verify that the software was installed successfully, check the
/opt/mapr/roles directory on each node. The software is installed in the
/opt/mapr directory and a file is created in
/opt/mapr/roles for every service that installs successfully. The following
example shows the /roles directory with services that installed
successfully:
Example
# ls -l /opt/mapr/roles
