Subject [jira] [Commented] (HDFS-9880) TestDatanodeRegistration fails occasionally
Date Tue, 01 Mar 2016 18:43:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15174163#comment-15174163
] 

Kihwal Lee commented on HDFS-9880:
----------------------------------

If I run this test case in a loop, the failure is reproduced in less than 10 runs. With the
timeout changed to 2000 (2 seconds), it passes all the time. The test-level timeout of 10
seconds should be removed. The test run-time is very close to 10 seconds.

> When {{testForcedRegistration}} calls {{waitForBlockReport()}}, it sometimes returns
false because the timeout is too short (100ms).
