------------------------------------------
Summary: Storm metrics do not work after upgrading Ambari to 2.1.2.
Key: AMBARI-14257
URL: https://issues.apache.org/jira/browse/AMBARI-14257
Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.1.2
Reporter: Aravindan Vijayan
Assignee: Aravindan Vijayan
Priority: Critical
Fix For: 2.2.0
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.
