[jira] [Updated] (HDFS-1828) TestBlocksWithNotEnoughRacks intermittently fails assert

     [ https://issues.apache.org/jira/browse/HDFS-1828?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matt Foley updated HDFS-1828:
-----------------------------

    Attachment: TestBlocksWithNotEnoughRacks.java.patch

As part of HDFS-1295, this patch caused TestBlocksWithNotEnoughRacks to pass in build PreCommit-HDFS-Build/346, whereas it had failed before.

Posted here for information, but I'm going to subordinate this bug to HDFS-1295 (which it was blocking) and submit a single patch to that Jira.

> In server.namenode.TestBlocksWithNotEnoughRacks.testSufficientlyReplicatedBlocksWithNotEnoughRacks 
> assert fails at curReplicas == REPLICATION_FACTOR, but it seems that it should go higher initially, and if the test doesn't wait for it to go back down, it will fail false positive.
