Subject [jira] Commented: (HDFS-537) DataNode uses ReplicaBeingWritten to support dfs writes/hflush
Date Wed, 02 Sep 2009 04:07:32 GMT

    [ https://issues.apache.org/jira/browse/HDFS-537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750258#action_12750258

Hairong Kuang commented on HDFS-537:

The current trunk and append-branch are not stable. All unit tests are passed except for TestFiDataTransferProtocol
which was caused by HDFS-565. Occasionally TestAppend2 (caused by HDFS-565), TestBackupNode(HDFS-192),
TestBlocksWithNotEnoughRacks (HDFS-586) fail.
