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: 841123 number_of_rows: 10000 close_scanner: false next_call_seq: 0

解决办法：
减少
hbase.client.scanner.caching
增加
hbase.rpc.timeout
