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

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.
