Subject [jira] [Commented] (HDFS-5451) add more debugging for cache rescan
Date Thu, 07 Nov 2013 22:59:17 GMT

Andrew Wang commented on HDFS-5451:
-----------------------------------

Cross-posting my comment from HDFS-5394 as a follow on for here:

bq. I'd like to see the LogVerificationAppender used in testUncachingBlocksBeforeCachingFinishes
too. This seems like it might be flaky though. What was wrong with the old approach that used
a barrier to force ordering?

> It would be nice to have message at DEBUG level that described all the decisions we made
for cache entries.  That way we could turn on this debugging to get more information.  We
should also store the number of bytes each PBCE wanted, and the number of bytes it got, plus
the number of inodes it got, and output those in {{listDirectives}}.
