Hi Fleming, That warning is harmless. It should recover after such things. If you ever see some fatal problems (crashes, data loss, corruption, etc) after such a thing let us know.
HBase should handle multiple clients writing to the same table fine. You will get better performance if they are writing to different regions (i.e. random data), as then the load is split between multiple region serving nodes. -n On Thu, Jul 2, 2009 at 9:28 PM, <[email protected]> wrote: > Hi there, > > Now I use HTable to put my oracle table data to HBASE. > In order to enhance the speed, I create a few HTable clients to put the > data. > It occured only some WARN like "WARN zookeeper.ClientCnxn: Exception > closing session", > not fetal error,evently I found there's no data increase in HBASE. > Any HBASE setting about the client connection limitation? > Or HBASE doesn't allow multiple clients write to the same table. > Any suggestion? > Thank you > > Fleming > > --------------------------------------------------------------------------- > TSMC PROPERTY > This email communication (and any attachments) is proprietary information > for the sole use of its > intended recipient.
