[jira] [Created] (HBASE-25735) Add target Region to connection
exceptions
Michael Stack created HBASE-25735:
-------------------------------------
Summary: Add target Region to connection exceptions
Key: HBASE-25735
URL: https://issues.apache.org/jira/browse/HBASE-25735
Project: HBase
Issue Type: Bug
Components: rpc
Reporter: Michael Stack
Assignee: Michael Stack
We spent a bit of time making it so exceptions included the remote host name. Looks like we can add the target Region name too with a bit of manipulation; will help figuring hot-spotting or problem Region on serverside. For example, here is what I was seeing recently on client-side when a RS was was timing out requests:

I wanted the region it was hitting. I wanted to know if it was a server problem or a Region issue. If clients only having issue w/ one Region, then I could focus on it.
After the PR the exception (from another context) looks like this:
{code}
org.apache.hadoop.hbase.ipc.CallTimeoutException: Call to address=127.0.0.1:12345, regionInfo=hbase:meta,,1.1588230740 failed on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: error
