Increase the value of hbase.client.scanner.timeout.period. Make sure that hbase.rpc.timeout is at least as large as hbase.scanner.timeout. Most likely, the client took too much time rendering the data in your terminal and the scanner in the HBase RegionServer memory was closed to free resources. When the client went to fetch the next batch of records, the regionserver informed your client that it already closed the scanner you were trying to use.
