Hi, I'm having following issues with triggering manually major compaction on selected regions via HBaseAdmin: 1. When I'm triggering major compaction on first region, which does not contains key, it's running normally - I see message in logs ([..]Large Compaction requested ... Because: User-triggered major compaction;[...]) and after some time it's executed (info in logs). Example region name: test,,1359115210217.7315770e499a47e0598849d8702ed202. 2. When I'm triggering major compaction on some chosen region (this one contains a key) I see no information as before, like it would not be triggered, although I'm not getting any errors or so. Thus, I'm not sure if compaction which will be executed is major or rather minor. Moreover, I've noticed that on one region which was previously (2h before) triggered for compaction, I've received only information about the end of compaction (Store: Completed major compaction of 3 file(s) in data of [...]). Example region name: test,\x00|@\x07\x00\x00\x0A\x19,1359529282226.aa16fae842a3e3f38a6ee75dc6a2941a. 3. How can I verify for sure that major compaction was really triggered? I've also read on forum that since 0.92 version MC is triggered asynchronously (is it?). 4. Why there is no such information in logs saying that major compaction was triggered or is rolling (logs on DEBUG at the moment)? 5. Where can I find some detailed information about major compaction itself?
