hbase协处理器统计行数

利用hbase的协处理器统计行数，抛出异常，信息如下：java.io.IOException: java.net.SocketTimeoutException: callTimeout=1200000, callDuration=1200209: Call to dataserver1/192.168.21.29:16020 failed on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: Call id=45, waitTime=599814, rpcTimeout=599808 row '20120701000022ws10fhjsae4de5903ed14af79c262179c13b4681' on table 'point' at region=point,20120701000022ws10fhjsae4de5903ed14af79c262179c13b4681,1551167443768.aeb0245aea508ecbcf7ad7b3f0b3c0d0., hostname=dataserver1,16020,1551337949226, seqNum=1819
