Kihwal Lee reassigned HDFS-4998: -------------------------------- Assignee: Kihwal Lee > TestUnderReplicatedBlocks fails intermittently > ---------------------------------------------- > > Key: HDFS-4998 > URL: https://issues.apache.org/jira/browse/HDFS-4998 > Project: Hadoop HDFS > Issue Type: Bug > Components: test > Affects Versions: 2.1.0-beta > Reporter: Kihwal Lee > Assignee: Kihwal Lee > > Looking at branch-2.1-beta jenkins build, this test case seems flaky. > First, addToInvalidates() is called against a block on a datanode. This > removes the dn from the BlockInfo in blocksMap. > At this point, raising the replication factor can cause the same node to be > picked. If the node has already deleted the block, it will work. If not, the > replication fails. When it fails, it will take at least the pending > replication timeout to reschedule, which is 5 minutes. But the test will > timeout before this and fail. > We could make it wait for the completion of actual block deletion. Or the > test timeout can be made a lot longer, but past jiras against this test case > indicate people want this to run faster. -- This message is automatically generated by JIRA.
