> Print row and table information when failed to get region location
> ------------------------------------------------------------------
>
> Key: HBASE-22283
> URL: https://issues.apache.org/jira/browse/HBASE-22283
> Project: HBase
> Issue Type: Improvement
> Components: Client, logging
> Affects Versions: 1.4.9, 2.0.5, 2.1.4
> Reporter: Yu Li
> Assignee: Yu Li
> Priority: Major
> Fix For: 3.0.0, 2.2.1, 1.5.1
>
>
> Currently when failed to get region location, especially when the
> {{RegionLocations}} returned is null in
> {{RpcRetryingCallerWithReadReplicas.getRegionLocations}} (we may see more
> useful message if there's an exception thrown), we only log the replica id
> w/o any detailed information about row and table, which makes the debugging
> difficult. Below is an example error message:
> {noformat}
> Caused by: org.apache.hadoop.hbase.client.RetriesExhaustedException: Can't
> get the location for replica 0
> at
> org.apache.hadoop.hbase.client.RpcRetryingCallerWithReadReplicas.getRegionLocations(RpcRetryingCallerWithReadReplicas.java:372)

> {noformat}
> And here we propose to improve this part.
