Review request for hive. Repository: hive-git Description ------- HIVE-15387: NPE in HiveServer2 webUI Historical SQL Operations section There is a race condition in the handling of the SQLOperationDisplay classes. Once an operation is complete/cancelled/timed out we move the SQLOperationDisplay from the live stack to the historical one. But the runtime is only updated once the state is set, after the SQLOperationDisplay is already among the historical queries. With this change the runtime will be "n/a" instead of an NPE being thrown. Diffs ----- service/src/resources/hive-webapps/hiveserver2/hiveserver2.jsp 6e899819cf33e149cbb2dbffb201348408330bbc Diff: https://reviews.apache.org/r/55932/diff/ Testing ------- Ran multiple queries and checked that they are still displayed correctly. Thanks, Barna Zsombor Klara
