Storm nimbus not coming up - two legacy jars

[#1]

Problem Description:

Unable to start storm nimbus from Ambari, throwing following error:

raise ExecutionFailed(err_msg, code, out, err) 
resource_management.core.exceptions.ExecutionFailed: Execution of 'ambari-sudo.sh ln -s /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common-*.jar /usr/hdp/current/storm-nimbus/lib/ambari-metrics-storm-sink.jar' returned 1. ln: target `/usr/hdp/current/storm-nimbus/lib/ambari-metrics-storm-sink.jar' is not a directory

Cause:

Two legacy jars under storm lib:

# ls -ld /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common* 
-rw-r--r-- 1 root root 1937430 May 11 15:57 /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common-2.4.1.0.22.jar 
-rw-r--r-- 1 root root 1933392 Nov 23 2016 /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common-2.4.2.0.136.jar

Solution:

As the Ambari version was 2.4.2 so, moved ambari-metrics-storm-sink-legacy-with-common-2.4.1.0.22.jar to a different location and started storm nimbus.
