Description

During incremental replication, if we split the events batch as follows, then the REPL LOAD on second batch throws NPE.

Batch-1: CREATE_TABLE(t1) -> ADD_PARTITION(t1.p1) -> DROP_PARTITION (t1.p1)

Batch-2: DROP_TABLE(t1) ->  CREATE_TABLE(t1) -> ADD_PARTITION(t1.p1) -> DROP_PARTITION (t1.p1)
