Anoop Sam John commented on HBASE-15831:
----------------------------------------
Why you need a filter? Can u use Scan setStart and setStop rows to set the
range? The issue is you are trying to fetch 500 rows in one RPC and there is
filters also.. So at server end, we might be touching many more rows in one
RPC call.. This eats up time and client side gets RPC time out and it retry.
You have to either increase the time outs or/and reduce the possible #rows
touch per scan rpc.

> I am getting following error when I am trying to scan hbase table in QED

> Caused by: org.apache.hadoop.hbase.exceptions.OutOfOrderScannerNextException:
> org.apache.hadoop.hbase.exceptions.OutOfOrderScannerNextException: Expected
> nextCallSeq: 1 But the nextCallSeq got from client: 0; request=scanner_id:

> I goggled and found if we add following properties we would not be getting
> above issue, but this property changes also did not help
> .set("hbase.client.pause","1000")
> .set("hbase.rpc.timeout","90000")
