Appy commented on HBASE-19457:
------------------------------

Still failing, less frequently on apache infra, but much more frequently on GCE 
infra. Will take a look.

> 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
