> Key: HIVE-20948
> URL: https://issues.apache.org/jira/browse/HIVE-20948
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 4.0.0
> Reporter: Eugene Koifman
> Assignee: László Pintér
> Priority: Major
> Attachments: HIVE-20948.01.patch, HIVE-20948.02.patch,
> HIVE-20948.03.patch, HIVE-20948.04.patch, HIVE-20948.05.patch,
> HIVE-20948.06.patch, HIVE-20948.07.patch

>
> Once HIVE-20823 is committed, we should investigate if it's possible to have
> compactor write directly to base_x_cZ or delta_x_y_cZ.
> For query based compaction: can we control location of temp table dir? We
> support external temp tables so this may work but we'd need to have non-acid
> insert create files with {{bucket_xxxxx}} names.
>
> For MR/Tez/LLAP based (should this be done at all?), need to figure out how
> retries of tasks will work. Just like we currently generate an MR job to
> compact, we should be able to generate a Tez job.
