hi, ALL. I recently encountered a problem that when HBase writes, there is an error in the log: "Batch mutation has a row that does not belong to this region" Org. apache. hadoop. hbase. regionserver. WrongRegionException: Requested row out of range for doMiniBatchMutation", Once this error occurs, the write speed of the cluster will slow down. In response to this error, I tried to fix it with the HBCK command, but it didn't work. The current version of HBase is hdp-2.5.0.0-1245, and the HBase version is 1.1.2.2.5. Have you ever met? How to solve it? Detailed error information is as follows: 2019-07-12 18:03:12,402 WARN [B.fifo.QRpcServer.handler=18,queue=18,port=16020] regionserver.HRegion: Batch mutation had a row that does not belong to this region org.apache.hadoop.hbase.regionserver.WrongRegionException: Requested row out of range for doMiniBatchMutation on HRegion Monitor_RowData_20190708,TaskCenterExecTime#201907102227016188725##d973ecd9-a81f-49e4-912f-dad5764c9690, 1562954418071.0b79b493d94b50e70a787b8ed90e1a99., startKey='TaskCenterExecTime#201907102227016188725##d973ecd9-a81f-49e4-912f-dad5764c9690', getEndKey()='TaskCenterMsgReceiveTps#201907081344007337702##f22b5214-37b5-4758-a0ac-cb7fb39b05bf', row='RabbitMQQueueReady#201907130202334532327##3b7604fc-6eda-4195-b601-29a52dcb9d0c' at org.apache.hadoop.hbase.regionserver.HRegion.checkRow(HRegion.java:5211) at org.apache.hadoop.hbase.regionserver.HRegion.checkAndPrepareMutation(HRegion.java:3879) at org.apache.hadoop.hbase.regionserver.HRegion.doMiniBatchMutation(HRegion.java:3040) at org.apache.hadoop.hbase.regionserver.HRegion.batchMutate(HRegion.java:2933) at org.apache.hadoop.hbase.regionserver.HRegion.batchMutate(HRegion.java:2875) at org.apache.hadoop.hbase.regionserver.RSRpcServices.doBatchOp(RSRpcServices.java:715) at org.apache.hadoop.hbase.regionserver.RSRpcServices.doNonAtomicRegionMutation(RSRpcServices.java:677) at org.apache.hadoop.hbase.regionserver.RSRpcServices.multi(RSRpcServices.java:2054) at org.apache.hadoop.hbase.protobuf.generated.ClientProtos$ClientService$2.callBlockingMethod(ClientProtos.java:32303) at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2127) at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:107) at org.apache.hadoop.hbase.ipc.RpcExecutor.consumerLoop(RpcExecutor.java:133) at org.apache.hadoop.hbase.ipc.RpcExecutor$1.run(RpcExecutor.java:108) at java.lang.Thread.run(Thread.java:745) ...

hi,everyone: When I use phoenix write on Gloable index table, I Find can't Write table with this speed 500/s。 but when I use phoenix write on table without inex. There is no problems. Write speed is High as hbase write speed。Why? My hdp is 2.4 phoenix version is 4.4 , I use jdbc write data in Tomcat server。 My HBase cluster is with seven region servers. Each region server have 8 g heapspace。 each Machine is 14g memory。 My hbase cluster parameter like this： when I Write data I find some phenomenon like this。 t first, the writing speed is very fast, a few minutes later, it becomes very slow 。I use ambari .Grafana It was the same as writing pressure from 19:12, but the amount of data received by Region server was normal for a few minutes, and then quickly became smaller again I Think The reason for the slow write of Phoenix is that it handles the index, but does not know how to adjust the parameters My hbase montor like this When slow I find this log in region server log WARN [B.defaultRpcServer.handler=78,queue=18,port=16020] ipc.RpcServer: (responseTooSlow): {"call":"Multi(org.apache.hadoop.hbase.protobuf.generated.ClientProtos$MultiRequest)","starttimems":1483770756522,"responsesize":1822,"method":"Multi","processingtimems":45257,"client":"192.168.0.57:50023","queuetimems":0,"class":"HRegionServer"} who can help me?
