Sankar Hariappan updated HIVE-19435:
------------------------------------
Description:
If the incremental dump have drop of partitioned table followed by
create/insert on non-partitioned table with same name, doesn't replicate the
data. Explained below.
Let's say we have a partitioned table T1 which was already replicated to target.
DROP_TABLE(T1)->CREATE_TABLE(T1) (Non-partitioned) -> INSERT(T1)(10)
After REPL LOAD, T1 doesn't have any data.
Same is valid for non-partitioned to partitioned and partition spec mismatch
case as well.
