 Description   

The client uses mysql java connector and commits after each insert. The client faced with the situation similar to that described in MCOL-984. Namely he has a table that fails to server any SELECT after the client adds a new 1 byte column. Here is the details of the error:
Error Code: 1815. Internal error: An unexpected condition within the query caused an internal processing error within InfiniDB. Please check the log files for more details. Additional Information: error in BatchPrimitiveProces

It occures that MCOL-984 PR fixes issue for bulk insert but doesn't handle single insertion case.
