Subject [jira] [Commented] (HDFS-3902) TestDatanodeBlockScanner is flaky, broke entirely after HDFS-3828
Date Wed, 12 Sep 2012 18:12:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3902?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454190#comment-13454190
] 

Eli Collins commented on HDFS-3902:
-----------------------------------

Nice debugging Andy.  +1 to this patch, let's pull the 2nd failure scenario you describe out
to another jira and address there.

The test failures are unrelated, I filed HDFS-3930 for TestBPOfferService. TestWebHDFS and
TestPersistBlocks both failed due to networking issue (connection refused to a grid machine).

> Since HDFS-3828 fixed the block scanner to not repeatedly rescan small blockpools, TestDatanodeBlockScanner
times out after 13 minutes in {{waitReplication}}.
