Sean Busbey commented on HBASE-15611:
-------------------------------------

h2. How do I tell if compactions are happening, programmatically from the shell?

{code}
hbase(main):104:0> list.each do |table| @hbase.admin(@formatter).instance_eval 
do p @admin.get_compaction_state(table).to_string end end
TABLE                                                                           
                                                                                
                                            
usertable

This looks a little too in-the-guts to me, so maybe first there should be an 
improvement jira that makes answering the question easier.
