hey, so you have discovered a particular 'trick' about how the HBase RPC works... at the lowest level there is only 1 socket for every thread to talk to all regionservers. Thus if you are sending a large amount of data to HBase you can see this bottlenecking.
It is highly likely there might be something interesting in the HRegionServer logs, perhaps the regionserver is blocking because it's trying to keep from being overrun (we ship with very conservative defaults). There was a recent thread about this too... the thread was titled "ideas to improve throughput of the base writting". -ryan On Thu, Jun 10, 2010 at 3:17 PM, Sujee Maniyam <[email protected]> wrote: > forgot to mention, that I am using hbase 0.20.4 >
