Subject [jira] [Commented] (HADOOP-8624) ProtobufRpcEngine should log all RPCs if TRACE logging is enabled
Date Thu, 26 Jul 2012 18:21:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13423321#comment-13423321

Todd Lipcon commented on HADOOP-8624:

The javadoc output must be unrelated - it says I fixed 2 warnings, but I didn't modify any
javadoc in this patch at all. I'll commit this momentarily.

> Since all RPC requests/responses are now ProtoBufs, it's easy to add a TRACE level logging
output for ProtobufRpcEngine that actually shows the full content of all calls. This is very
handy especially when writing/debugging unit tests, but might also be useful to enable at
runtime for short periods of time to debug certain production issues.
