> I have created table A using {{HBaseAdmin.createTableAsync()}} with 2000 pre-split regions, the expectation was client RPC call does not get blocked and i had only used 5 minutes as RPC socket timeout value.
> It appears from logs/code that clients gets blocked (honoring the {{hbase.rpc.timeout}} value), times out after 5 minutes, master nio channel gets closed (related to client which invoked the createAsyncTable operation), put region entries in inconsistent state in META, meaning {{info:server}} is marked as null and AssignmentManager gets null server value (which causes NPE) and causes to table creation fail, i could not succeed until changing the {{hbase.rpc.timeout}} value to 15 minutes and created tables one at a time (each table has more than 2K pre-split regions in it)
> Please refer the logs.
