I checked the exception, unable to reproduce in local. While getting root exception, its setting to null Cause if not available, as its filtering only known type of exception. If any other happens, it will cause this issue.
We need fix that fix org.apache.hadoop.hdds.scm.client.HddsClientUtils#checkForException to have null check before assigning "t = t.getCause()" to avoiding setting null.
This can be taken up as another JIRA issue.
