ya, i no jobs are seen in that jobtracker page, under RUNNING JOBS it is
none, under FINISHED JOBS it is none,FAILED JOBS it is none . its just like
no job is running. In eclipse i could see during mapreduce program running,
as you said "LOcalJobRunner", may be Eclipse is merely launchin

What Suraj said. Look in the coprocessor package. There are some

Andy,
Some detail on the current compaction algorithm. Major compactions can be
triggered in 3 ways:
1) User requested : e.g. From the shell
2) Size based : compact when file <= sum(smaller_files) *
'hbase.hstore.compaction.ratio'
This is the normal minor compaction logic. It will upgrade to a
Coprocessors are available with 0.92 which now has a release candidate (RC0).
So - you can probably try and build 0.92 RC0 to test this functionality out.

Thanks Mikhail. That's very helpful information.
We followed some of the advice that I believe was posted to this list in the
past to schedule major compactions manually to run during off-peak times. That
has gone very well for us, except when failures happen it seems we end up not

Hi Andy,
We don't persist manual compaction requests across server restarts, so if
e.g. a major compaction was requested manually and the regionserver
crashed, the new regionserver that picks up that region will not know about
the major compaction request. For automatic compactions, however,
