> This is a very serious condition, After this exception thrown, the exclusive
> lock held by ModifyTableProcedure was never released. All the procedure
> against this table were blocked. Until the master restarted, and since the
> lock info for the procedure won't be restored, the other procedures can go
> again, it is quite embarrassing that a bug save us...(this bug will be fixed
> in HBASE-20846)
> I tried to reproduce this one using the test case in HBASE-20921 but I just
> can't reproduce it.
> A easy way to resolve this is add a try catch, making sure no matter what
> happens, the table's exclusive lock can always be relased.
