I am importing data into Hbase with a client running 10 threads. I
explicitly call 'flushCommit' from each thread (after a few thousand puts)
Here is the thread-dump:
"pool-1-thread-20" prio=10 tid=0x0000000041072800 nid=0x17d8 in

and so on...
Is this is a known issue? otherwise I can open a ticket.
