The default configuration is (likely) only using one thread for
performing compactions (really, one thread for small and one thread for
big compactions). As such, yes, compactions in one RegionServer would be
performed serially.
But, don't forget, you probably have multiple RegionServers which all
host regions.

Hi,
As far as I understand, a compaction storm occurs when multiple regions of the
same region server perform compaction.
It looks like, from watching hbase UI that within a region server, compaction
is done serially for a specific table.(one region at a time)
So does this mean that a compaction storm can happen only if you have more than
one table?
