[jira] [Updated] (HDFS-11660) TestFsDataset#testPageRounder fails
intermittently with AssertionError
[ https://issues.apache.org/jira/browse/HDFS-11660?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Wang updated HDFS-11660:
-------------------------------
Attachment: HDFS-11660.001.patch
Mockito mocking isn't threadsafe, so I think this happens when we insert the mock for the heartbeat. Added a semaphore to pause all the BPOS threads before mocking, and unpause after.
