Vaibhav Gumashta updated HIVE-16172: ------------------------------------ Resolution: Fixed Fix Version/s: 2.2.0 Status: Resolved (was: Patch Available) Committed. Thanks [~taoli-hwx] > Switch to a fairness lock to synchronize HS2 thrift client > ---------------------------------------------------------- > > Key: HIVE-16172 > URL: https://issues.apache.org/jira/browse/HIVE-16172 > Project: Hive > Issue Type: Bug > Reporter: Tao Li > Assignee: Tao Li > Fix For: 2.2.0 > > Attachments: HIVE-16172.1.patch > > > A synchronized block is used in > "org.apache.hive.jdbc.HiveConnection.SynchronizedHandler.invoke(Object, > Method, Object[])" to synchronize the client invocations. The problem is that > it does not guarantee any fairness. One issue we were seeing is that a > cancellation request was not able to be issued to HS2 until all the > getOperationStatus() calls are finished from a while loop. Thus the > cancellation cannot take effect. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
