Ted Yu commented on HBASE-4552:
-------------------------------

After applying the consolidated patch, I got:
{code}

For TRUNK, there is no such error.

> Currently the bulk load API simply imports one HFile at a time. With multi-column-family
support, this is inappropriate, since different CFs show up separately. Instead, the IPC endpoint
should take a of CF -> HFiles, so we can online them all under a single region-wide lock.
