Pengcheng Xiong reassigned HIVE-14925: -------------------------------------- Assignee: Pengcheng Xiong > MSCK repair table hang while running with multi threading enabled > ----------------------------------------------------------------- > > Key: HIVE-14925 > URL: https://issues.apache.org/jira/browse/HIVE-14925 > Project: Hive > Issue Type: Bug > Components: CLI > Affects Versions: 2.2.0 > Reporter: Ratheesh Kamoor > Assignee: Pengcheng Xiong > Priority: Critical > > MSCK REPAIR TABLE hanging while running with multi-threading enabled > (default). I think it is because of a major design flaw in how thread pool > implemented in HiveMetaSoreChecker class / checkPartitionDirs method. This > method has a thread pool which register Callable but callable makes a > recursive call to checkPartitionDirs method again. This code will hang when > number of directories is more than thread pool size. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
