Zhiyuan Yang updated HIVE-15570: -------------------------------- Attachment: HIVE-15570.2.patch Same exception may be thrown in following cases and is hard to debug. 1. llap mode is used but there is no llap daemon 2. llap mode is used but llap daemon is during recovery 3. container mode is used but hive.llap.client.consistent.splits is true In the new patch, hive.llap.client.consistent.splits won't be effective if container mode is used. If llap mode is used but there is no running daemon, we fall back to locations provided by splits. Then If there is no llap daemon at all, LlapTaskSchedulerService will detect this and report "No LLAP Daemons are running"; or if llap daemon finish recovery, query can still succeed. > LLAP: Exception in HostAffinitySplitLocationProvider when running in > container mode > ----------------------------------------------------------------------------------- > > Key: HIVE-15570 > URL: https://issues.apache.org/jira/browse/HIVE-15570 > Project: Hive > Issue Type: Bug > Components: llap > Reporter: Rajesh Balamohan > Assignee: Zhiyuan Yang > Priority: Minor > Attachments: HIVE-15570.1.patch, HIVE-15570.2.patch > > > Sometimes user might prefer to run with "hive.execution.mode=container" mode > when LLAP is stopped.
