stack commented on HBASE-3743:
------------------------------
As a workaround, we could run a script external to hbase that would first
elicted the set of regions in a cluster and then per region, set in motion a
major compaction waiting on completion before moving to the next region (Script
could check hdfs and count storefiles in the region to figure completion of
region major compaction). The script could be run from cron or, as per the
painting of the golden gate legend, once we'd gotten to the end of the
bridge/table, we would loop around and start in again on the first region, in
perpetuum.
