Jesse Yates commented on HBASE-7725:
------------------------------------
bq. Parameter name should be attributes, right ?
Yup.
bq. Would the attributes be String or Map ?
String will lead to munging and map will often be too heavy weight. I don't
want to force it - this is an internal hook, so you know what you are passing -
you can cast it when you get it.
bq. Looks like attributes parameter isn't passed on.
Good catch.
bq. I think the requests would be queued. So please modify the @return.
Definitely.
bq. It would be nice to put trunk patch on review board.
Its, unfortunately, going to be more than a little bit different. But yeah,
I'll post one up soon

> You can request that a compaction be started, but you can't be sure when that
> compaction request completes. This is a simple update to the
> CompactionRequest interface and the compact-split thread on the RS that
> doesn't actually impact the RS exposed interface.
> This is particularly useful for CPs so they can control starting/running a
> compaction.
