Review request for Ambari, Dmytro Sen, Sumit Mohanty, Sid Wagle, and Vitalyi
Brodetskyi.
Bugs: AMBARI-14257
https://issues.apache.org/jira/browse/AMBARI-14257
Repository: ambari
Description (updated)
-------
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_component>/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.
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
