Subject [HBASE] [Freeing Up Region and/or merging region]
Date Fri, 26 Aug 2011 17:27:33 GMT
On suggestion by JDC

Creating a separate thread

On a smaller cluster pre allocating a certain memory to region leads to
continuous increase in heap space usage
with increasing usage.

Hence clean up of data is performed by me.

But region having no data does not get de allocated automatically and it
still occupies the preallocated memory.

I was a looking for a clean mechanism to achieve that.

Either merging two continuous empty region or deleting a region cleanly.

Unfortunately my efforts to mess directly with metadata and cleaning up
of region dirs on cluster
has resulted in my tables getting corrupt.

Basically any way to cleanly get back those precious memory.
