Gopal V commented on HIVE-19124: -------------------------------- Yes, this is true even today, but it will move away with standalone-metastore. I just realized there's one dropped issue in the code from [~ekoifman] to address. TxnUtils.updateForCompactionQuery is yet another codepath, which we shouldn't need - the TxnUtils.createValidCompactWriteIdList goes further ahead than that. Basically if low-water mark is x and x+1, x+2 etc are aborted, your impl only compactors till x. > implement a basic major compactor for MM tables > ----------------------------------------------- > > Key: HIVE-19124 > URL: https://issues.apache.org/jira/browse/HIVE-19124 > Project: Hive > Issue Type: Bug > Components: Transactions > Reporter: Sergey Shelukhin > Assignee: Sergey Shelukhin > Priority: Major > Labels: mm-gap-2 > Attachments: HIVE-19124.01.patch, HIVE-19124.02.patch, > HIVE-19124.03.patch, HIVE-19124.03.patch, HIVE-19124.04.patch, > HIVE-19124.05.patch, HIVE-19124.06.patch, HIVE-19124.07.patch, > HIVE-19124.patch > > > For now, it will run a query directly and only major compactions will be > supported. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
