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
ycsb
ycsb_workloade
3 row(s) in 0.0080 seconds
"NONE"
"NONE"
"NONE"
=> ["usertable", "ycsb", "ycsb_workloade"]
hbase(main):105:0> major_compact "ycsb_workloade"
0 row(s) in 0.0950 seconds
hbase(main):106:0> list.each do |table| @hbase.admin(@formatter).instance_eval
do p @admin.get_compaction_state(table).to_string end end
TABLE
usertable
ycsb
ycsb_workloade
3 row(s) in 0.0090 seconds
"NONE"
"NONE"
"MAJOR"
=> ["usertable", "ycsb", "ycsb_workloade"]
{code}
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.
