mahesh kumar behera updated HIVE-21213:
---------------------------------------
Description: The current implementation of compaction uses the txn id in
the directory name. This is used to isolate the queries from reading the
directory until compaction has finished and to avoid the compactor marking used
earlier. In case of replication, the directory can not be copied as the txn
list at target may be different from source. So conversion logic is required to
create a new directory with valid txn at target and dump the data to the newly
created directory. (was: The current implementation of compaction makes use of
