Subject [jira] Updated: (HDFS-733) TestBlockReport fails intermittently
Date Thu, 05 Nov 2009 01:53:32 GMT

     [ https://issues.apache.org/jira/browse/HDFS-733?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Konstantin Boudnik updated HDFS-733:

    Attachment: HDFS-733.patch

New patch essentially run a separate check thread which starts new DN and waits for the replication
of all blocks to finish. {{DFSTestUtil.waitReplication}} which waits for the finish of replication
seems to be flawed because on large blocks it reports the end of replication prematurely,
which might be a bug.

The main thread waits until a temp. replica will appear on the new DN and checks for number
of blocks pending replication.

This seems to be working properly.
