Description
We do not restrict user from creating a table having column family starting with '_'.
So when user creates a table in such a way then LoadIncrementalHFiles will skip those family data to load into the table.
// Skip _logs, etc if (familyDir.getName().startsWith("_")) continue;
I think we should remove that check as I do not see any _logs directory being created by the bulkload tool in the output directory.
