Yu Li created HBASE-22283:
-----------------------------
Summary: 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: 2.1.4, 2.0.5, 1.4.9
Reporter: Yu Li
Assignee: Yu Li
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

And here we propose to improve this part.
