----------------------------------
Summary: Ozone: OzoneRestClientException swallows exceptions which
makes client hard to debug failures
Key: HDFS-12489
URL: https://issues.apache.org/jira/browse/HDFS-12489
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Reporter: Weiwei Yang
Assignee: Weiwei Yang
There are multiple try-catch places swallow exceptions when transforming some
other exception to {{OzoneRestClientException}}. As a result, when client runs
into such code paths, they lose track of what was going on which makes the
debug extremely difficult. See below example
{code}
bin/hdfs oz -listBucket http://15oz1.fyre.ibm.com:9864/vol-0-84022 -user wwei
Command Failed : {"httpCode":0,"shortMessage":"Read timed
out","resource":null,"message":"Read timed
out","requestID":null,"hostName":null}
{code}
the returned message doesn't help much on debugging where and how it reads
timed out.
