Janos Gub commented on HBASE-17436:
-----------------------------------
My idea is to have each region's state available through JMX. I am thinking in
reporting the string state of each region as a metric.
First I was planning to place it in the HRegion's metrics (MetricsRegionSource,
etc), but as regions are not aware of their state, now I am planning to put it
somehow the AssignmentManager's metrics. To be more precise, creating a
MetricsSource for RegionState and aggregating it in the AssignmentManager's
metrics.
Let me come up with an implementation in the following days and discuss it.
> Add facility to provide more information for Other Regions seen on Master UI

> [~rpednekar] and I were looking at a case where the count displayed under
> Other Regions was high (~1200).
> Since the table page just maintains a count instead of List of region names,
> it is very difficult for user to determine which regions belong to this
> category.
> We should provide facility to provide more details for this category (LOG,
> JMX, etc).
