Review request for hive. Bugs: HIVE-13099 https://issues.apache.org/jira/browse/HIVE-13099 Repository: hive-git Description ------- To support display of live operations in the WebUI, we record SQLOperations (in {{liveSqlOperations}}). However, to support historic operations, we save all operations in {{historicSqlOperations}}, including non-SQLOperations which do not have display entries in liveSqlOperations. This leads to a race condition depending on whether sessions use non-sql operations. Reproduce-able by issuing a 'set' operation. Diffs ----- service/src/java/org/apache/hive/service/cli/operation/OperationManager.java 96c01de40fa581f1583fc3f9a93a2c71355ebc04 Diff: https://reviews.apache.org/r/43785/diff/ Testing ------- Thanks, Mohit Sabharwal
