LDI with columnstore_use_import_for_batchinsert On failed

Build tested: 1.4.3-1 BB nightly

engine commit:
f843e98

LDI of 1gb orders or lineitem failed with the following error:

load data infile "/data/qa/source/dbt3/1g/orders.tbl" into table orders fields terminated by "|";
ERROR 1030 (HY000): Got error -1 "Internal error < 0 (Not system error)" from storage engine Columnstore

This occurred only when columnstore_use_import_for_batchinsert is set to ON.
cpimport itself for the same datasets also worked fine.

OAM showed the PM1 is in DEGRADED state. It is a single-node stack.

The tables has data compression on

The same test on the build I downloaded from buildbot yesterday (engine commit: 8588678) did not have this issue.
