------------------------------------
Summary: Print too slow/big scan's operation_id in region server
log
Key: HBASE-26479
URL: https://issues.apache.org/jira/browse/HBASE-26479
Project: HBase
Issue Type: Improvement
Components: regionserver
Reporter: Xuesen Liang
Assignee: Xuesen Liang
Tracing is very important in large-scale distributed systems.
The attribute *__operation.attributes.id_* of a scan request can be used as
trace id between hbase client and region server.
We should print operation id in region server's log if the scan request is too
slow or too big.
It will be very helpful for finding problematic requests.
