---------------------------------------
Summary: ACID: use a new write id for compaction's output instead
of the visibility id
Key: HIVE-21757
URL: https://issues.apache.org/jira/browse/HIVE-21757
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 4.0.0
Reporter: Vaibhav Gumashta
HIVE-20823 added support for running compaction within a transaction. To
control the visibility of the output directory, it uses
base_writeId_visibilityId, where visibilityId is the transaction id of the
transaction that the compactor ran in. Perhaps we can keep using the
base_writeId format, by allocating a new writeId for the compactor and creating
the new base/delta with that.
