Subject [jira] [Commented] (HBASE-4014) Coprocessors: Flag the presence of coprocessors in logged exceptions
Date Sun, 25 Sep 2011 07:15:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13114168#comment-13114168

Ted Yu commented on HBASE-4014:
-------------------------------

@Gary:
When I discovered why the original TestRegionServerCoprocessorExceptionWithAbort failed indeterministically,
I thought about the same idea. However, I kept the formation that Eugene created and used
the approach described above.
In current formation, we could have asserted that the other region server was left intact.

However, I fully respect your decision.
Let me bring 0.92 on par with TRUNK. You can determine the final formation.

> For some initial triage of bug reports for core versus for deployments with loaded coprocessors,
we need something like the Linux kernel's taint flag, and list of linked in modules that show
up in the output of every OOPS, to appear above or below exceptions that appear in the logs.
