             Summary: Ozone: Fix swallow exceptions which makes hard to debug failures
                 Key: HDFS-12583
                 URL: https://issues.apache.org/jira/browse/HDFS-12583
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin


There are some places that swallow exceptions that makes client hard to debug the failure. For example, if we get xceiver client from xceiver client manager error, we only get the error info like this:
{noformat}
org.apache.hadoop.ozone.web.exceptions.OzoneException: Exception getting XceiverClient.

{noformat}
The error exception stack is missing.
