Hudson commented on HBASE-13831: -------------------------------- SUCCESS: Integrated in HBase-1.2 #132 (See [https://builds.apache.org/job/HBase-1.2/132/]) HBASE-13831 TestHBaseFsck#testParallelHbck is flaky against hadoop 2.6+ (Stephen Jiang) (tedyu: rev 86d30e0bfe62098415a41af2ae7f534488919f24) * hbase-server/src/test/java/org/apache/hadoop/hbase/util/TestHBaseFsck.java > TestHBaseFsck#testParallelHbck is flaky against hadoop 2.6+ > ----------------------------------------------------------- > > Key: HBASE-13831 > URL: https://issues.apache.org/jira/browse/HBASE-13831 > Project: HBase > Issue Type: Bug > Components: hbck, test > Affects Versions: 2.0.0, 1.1.0, 1.2.0 > Reporter: Stephen Yuan Jiang > Assignee: Stephen Yuan Jiang > Priority: Minor > Fix For: 2.0.0, 1.2.0, 1.1.1 > > Attachments: HBASE-13831.patch > > > Running TestHBaseFsck#testParallelHbck is flaky against HADOOP-2.6+ > environment. The idea of the test is that with when 2 HBCK operations are > running simultaneously, the 2nd HBCK would fail with no-retry because > creating lock file would fail due to the 1st HBCK already created. However, > with HADOOP-2.6+, the FileSystem#createFile call internally retries with > AlreadyBeingCreatedException (see HBASE-13574 for more details: "It seems > that test is broken due of the new create retry policy in hadoop 2.6. > Namenode proxy now created with custom RetryPolicy for > AlreadyBeingCreatedException which is implies timeout on this operations up > to HdfsConstants.LEASE_SOFTLIMIT_PERIOD (60seconds).") > When I run the TestHBaseFsck#testParallelHbck test against HADOOP-2.7 in a > Windows environment (HBASE is branch-1.1) multiple times, the result is > unpredictable (sometime succeeded, sometime failed - more failure than > succeeded). > The fix is trivial: Leverage the change in HBASE-13732 and reduce the max > wait time to a smaller number. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
