Nick Bailey updated CASSANDRA-1516:
-----------------------------------
Attachment: 0001-Mbean-for-tracking-progress-on-a-pending-drain.patch
Added a basic patch that shows drain progress. Simply shows the number of
tables left to flush and the number of CFs left to flush in the current table.
> Explicitly expose ongoing per-node tasks (like compactions, repair, etc) and
> est. % done

> so major compaction, read-only compaction, repair, drain, and bootstrap are
> the on-node tasks I'm pretty sure make sense to be exposed in this way.
> snapshotting might make sense too.
> some of these can be "detected" using heuristics on the number of tasks alive
> in different stages, but it would be preferable if it could be made more
> clear.
> the interface should allow multiple tasks and respective percentages to be
> ongoing at the same time, especially since some tasks (like repair)
> implicitly kick off other sub-tasks (compaction) and both of them would
> normally show up at the same time.
