[jira] [Updated] (AMBARI-14257) Storm metrics do not work after
upgrading Ambari to 2.1.2.
[ https://issues.apache.org/jira/browse/AMBARI-14257?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aravindan Vijayan updated AMBARI-14257:
---------------------------------------
Description:
Problem
Storm metrics do not work after upgrading from versions < 2.1.1 to 2.1.2. ClassNotFound exception seen in the logs when storm metrics reporter class is accessed.
Bug
Storm lib directory is usually found in /usr/hdp/current/storm-nimbus/lib. In the code we try to delete the link from /usr/lib/storm/lib which is not present. Hence, we never update the symlink in the actual location thus causing a stale symlink.
Fix
Change the symlink deletion logic to look at the correct location. Also fix a bug in resource_management.system module where the action='delete' for Links must call the os.path.lexists rather than os.path.exists to return true for broken symlinks
