Syed Shameerur Rahman commented on HIVE-23737: ---------------------------------------------- [~abstractdog] Could you please review the PR? > LLAP: Reuse dagDelete Feature Of Tez Custom Shuffle Handler Instead Of LLAP's > dagDelete > --------------------------------------------------------------------------------------- > > Key: HIVE-23737 > URL: https://issues.apache.org/jira/browse/HIVE-23737 > Project: Hive > Issue Type: Improvement > Components: llap > Reporter: Syed Shameerur Rahman > Assignee: Syed Shameerur Rahman > Priority: Major > Labels: pull-request-available > Time Spent: 1h 20m > Remaining Estimate: 0h > > LLAP have a dagDelete feature added as part of HIVE-9911, But now that Tez > have added support for dagDelete in custom shuffle handler (TEZ-3362) we > could re-use that feature in LLAP. > There are some added advantages of using Tez's dagDelete feature rather than > the current LLAP's dagDelete feature. > 1) We can easily extend this feature to accommodate the upcoming features > such as vertex and failed task attempt shuffle data clean up. Refer TEZ-3363 > and TEZ-4129 > 2) It will be more easier to maintain this feature by separating it out from > the Hive's code path. -- This message was sent by Atlassian Jira (v8.3.4#803005)
