Step 4: 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
total 0
-rwxr-xr-x 1 root root 0 Aug 29 17:59 fileserver
-rwxr-xr-x 1 root root 0 Aug 29 17:58 tasktracker
-rwxr-xr-x 1 root root 0 Aug 29 17:58 webserver
-rwxr-xr-x 1 root root 0 Aug 29 17:58 zookeeper
