-------------------------------------

Sean Busbey hmm.. could it be that the patch gets stuck somehow and can't be run, even if
renamed? I try to restart the patch manually but it fails immediately.

tar: This does not look like a tar archive

If you're manually running the precommit job, then you should be able to rerun it without
a rename (the duplicate submission check is done by the admin job, not the individual precommit
jobs).

the "not a tar archive" error looks like an error with downloading some tool; probably a redirect
not getting followed. lemme see if it's something simple I can fix now.

> In order to make sure that compactions are fully up to date it would be nice to have
metrics on:
> * Max storefile age
> * Min storefile age
> * Average storefile age
> * Number of reference files
> If we could have those metrics per region and per regionserver it would be awesome.
