Alan Gates updated HIVE-8258: ----------------------------- Attachment: HIVE-8258.2.patch > Compactor cleaners can be starved on a busy table or partition. > --------------------------------------------------------------- > > Key: HIVE-8258 > URL: https://issues.apache.org/jira/browse/HIVE-8258 > Project: Hive > Issue Type: Bug > Components: Transactions > Affects Versions: 0.13.1 > Reporter: Alan Gates > Assignee: Alan Gates > Priority: Critical > Attachments: HIVE-8258.2.patch, HIVE-8258.patch > > > Currently the cleaning thread in the compactor does not run on a table or > partition while any locks are held on this partition. This leaves it open to > starvation in the case of a busy table or partition. It only needs to wait > until all locks on the table/partition at the time of the compaction have > expired. Any jobs initiated after that (and thus any locks obtained) will be > for the new versions of the files. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
