Appy commented on HBASE-19457:
------------------------------
Let me put it in a more general way where understanding of ProcedureV2 is not
required.
Truncating table:
....
delete region states from meta
delete table state from meta
....
add new regions to meta with state null.
....crash
....recovery: TableStateManager treats table with null state as ENABLED. AM
treats regions with null state as offline. Combined result - AM starts
assigning the new regions from incomplete truncate operation.
Fix: Mark table as disabled instead of deleting it's state.
