-----------------------------

             Summary: Add client side property to allow logging details for batch errors
                 Key: HBASE-15711
                 URL: https://issues.apache.org/jira/browse/HBASE-15711
             Project: HBase
          Issue Type: Bug
            Reporter: Yu Li
            Assignee: Yu Li


Recently we observed below error message on client side when put process blocked:

2016-04-26 10:27:11,707 ERROR [Sink: Unnamed (1/1)] com.alibaba.search.blink.streaming.connector.hbase.HBaseOutputFormat: Doing mutation failed

And checking RS logs we found nothing noticable. After adding some logging to show the detailed exception, it turns out something went wrong in one of our coprocessors:

2016-04-26 12:03:13,776 ERROR [Sink: Unnamed (1/1)] org.apache.hadoop.hbase.client.AsyncProcess: Exception occurred! Exception details: [java.io.IOException: java.io.IOException: notify meta has not load success.

        at org.apache.hadoop.hbase.regionserver.HRegion.batchMutate(HRegion.java:2865)
{noformat}

So in this JIRA we propose to add a property to allow logging detailed exception stacktrace rather than statistics for batch errors, and I believe this would be useful for debugging in some cases.
