--------------------------------
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.
