Subject 答复: what in regionserver's Used Heap
Date Fri, 23 May 2014 06:30:58 GMT
Hi Ted

I have checked regionsever:60030/rs-status#regionMemstoreStats. Memstore and Cache Size is
very small.
But Used Heap is very large. 
Is there Any other thing in the Used Heap, and use lots of heaps? 

Thanks

On regionsever:60030/rs-status#regionMemstoreStats, you should be able to
see how much memstore each region uses.

You can also use ganglia, etc to view the metrics.
See http://hbase.apache.org/book.html#hbase_metrics (15.4.4.3 and 15.4.4.7)

Cheers
