Request to Improve Error Handling for Table Locks

This is a request to improve an error handling message when the following occurs:

When trying to run multiple inserts in parallel, one can see an error like the following:

SQLSTATE[HY000]: General error: 1030 Got error -1 "Internal error < 0 (Not system error)" from storage engine Columnstore

Now this can be expected behavior, but is a little hard to figure out what is going on by the above message.

In the error log, we see it is due to a table lock:

Error: Failed to acquire Table Lock of schema_name.table_name; Table currently locked by process-cpimport; pid-1337; session--1....

Thus it would be quite helpful if we could see some of the lock information in the returned error.
