Appy updated HBASE-19457:
-------------------------
Description:
Trying to explain the bug in a more general way where understanding of
ProcedureV2 is not required.
Truncating table operation:
....
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.
----
*patch1*
Just added some logging to help with debugging:
- 60s was too less time, increased timeout
- Added some useful log statements
