Daniel Dai commented on HIVE-17426: ----------------------------------- It sounds like there will be no parallel task run with explain/repldump no matter the value of canExecuteInParallel(). Then we don't need to make them standout. We only need to disable fetch/ddl for now until it is fixed. > Execution framework in hive to run tasks in parallel > ---------------------------------------------------- > > Key: HIVE-17426 > URL: https://issues.apache.org/jira/browse/HIVE-17426 > Project: Hive > Issue Type: Improvement > Components: HiveServer2 > Affects Versions: 3.0.0 > Reporter: anishek > Assignee: anishek > Fix For: 3.0.0 > > Attachments: HIVE-17426.0.patch, HIVE-17426.1.patch, > HIVE-17426.2.patch, HIVE-17426.3.patch, HIVE-17426.4.patch, HIVE-17426.5.patch > > > the execution framework currently only runs MR / Spark Tasks in parallel > when {{set hive.exec.parallel=true}}. > Allow other types of tasks to run in parallel as well to support replication > scenarios in hive. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
