Eugene Koifman commented on HIVE-19124: --------------------------------------- Hold on. We already have a mechanism for compactor to make sure it doesn't compact above an open txn: TxnUtils.createValidCompactWriteIdList() . This reinvents the wheel and add a new one to do the same thing in the Reader list. Why is this good? > 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)
