Bhupendra Kumar Jain commented on HBASE-14366:
----------------------------------------------
In the test cases there are 2 data lines (one with valid vis expression and
another with invalid vis expression) each having 2 columns. After the bulk
load happens, the invalid line will be skipped as bad line. Test case compares
the actual KV count written in HFile with expected KV count to ensure that
invalid vis expression KVs are skipped
{code}
assertTrue(String.format(
"KV count in output hfile=<%d> doesn't match with expected KV
count=<%d>", actualKVCount,
expectedKVCount), actualKVCount == expectedKVCount);
{code}
> NPE in case visibility expression is not present in labels table during
> importtsv run
