Hudson commented on HDFS-1562: ------------------------------ Integrated in Hadoop-Hdfs-trunk #650 (See [https://builds.apache.org/hudson/job/Hadoop-Hdfs-trunk/650/]) > Add rack policy tests > --------------------- > > Key: HDFS-1562 > URL: https://issues.apache.org/jira/browse/HDFS-1562 > Project: Hadoop HDFS > Issue Type: Test > Components: name-node, test > Affects Versions: 0.23.0 > Reporter: Eli Collins > Assignee: Eli Collins > Attachments: hdfs-1562-1.patch, hdfs-1562-2.patch, hdfs-1562-3.patch, > hdfs-1562-4.patch, hdfs-1562-5.patch > > > The existing replication tests (TestBlocksWithNotEnoughRacks, > TestPendingReplication, TestOverReplicatedBlocks, TestReplicationPolicy, > TestUnderReplicatedBlocks, and TestReplication) are missing tests for rack > policy violations. This jira adds the following tests which I created when > generating a new patch for HDFS-15. > * Test that blocks that have a sufficient number of total replicas, but are > not replicated cross rack, get replicated cross rack when a rack becomes > available. > * Test that new blocks for an underreplicated file will get replicated cross > rack. > * Mark a block as corrupt, test that when it is re-replicated that it is > still replicated across racks. > * Reduce the replication factor of a file, making sure that the only block > that is across racks is not removed when deleting replicas. > * Test that when a block is replicated because a replica is lost due to host > failure the the rack policy is preserved. > * Test that when the execss replicas of a block are reduced due to a node > re-joining the cluster the rack policy is not violated. > * Test that rack policy is still respected when blocks are replicated due to > node decommissioning. > * Test that rack policy is still respected when blocks are replicated due to > node decommissioning, even when the blocks are over-replicated. -- This message is automatically generated by JIRA.
