-------------------------------------
Summary: RpcLogDetails' Message can become corrupt before log is
consumed
Key: HBASE-28175
URL: https://issues.apache.org/jira/browse/HBASE-28175
Project: HBase
Issue Type: Bug
Reporter: Ray Mattingly
Assignee: Ray Mattingly
The RpcLogDetails class represents a slow (or large) log event which will later
be consumed by the SlowLogQueueService.
Right now the RpcLogDetails' param field points to the slow call's Message, and
this Message is backed by a CodedInputStream which may be overwritten before
the given log is consumed. This overwriting of the Message may result in slow
query payloads for which the metadata derived post-consumption is inaccurate.
To solve this bug I think we need to copy the Message in the RpcLogDetails
constructor. I have this bug reproduced in a QA environment and will test out
this idea and open a PR shortly if the test results are promising.
