             Summary: Acid table bootstrap replication needs to handle directory created by compaction with txn id
                 Key: HIVE-21213
                 URL: https://issues.apache.org/jira/browse/HIVE-21213
             Project: Hive
          Issue Type: Sub-task
          Components: Hive, HiveServer2, repl
            Reporter: mahesh kumar behera
            Assignee: mahesh kumar behera


The current implementation of compaction makes use of compaction to use the txn id in the directory name. This is used to isolate the queries from reading the directory until compaction has finished. 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.
