Also the regionserver keeps throwing exceptions like 2014-09-17 06:56:07,151 DEBUG [RpcServer.handler=10,port=60020] regionserver.ServerNonceManager: Conflict detected by nonce: [43871278468062569 89:2793719453824938427], [state 0, hasWait false, activity 06:55:41.091] 2014-09-17 06:56:07,151 DEBUG [RpcServer.handler=10,port=60020] regionserver.ServerNonceManager: Conflict detected by nonce: [43871278468062569 89:843474753753473839], [state 0, hasWait false, activity 06:55:41.094]
Are we sending data too fast? Is there a client side setting or a server side setting we need to look at to alleviate this? Again this was never a problem with HBase 0.94 cluster. We are calling the batch API in a List<> of 1000 increment and we do approx 30000 Increments (30 batches) at a time. -Vinay On Sep 16, 2014, at 11:24 PM, Vinay Gupta <[email protected]> wrote: > >> >> Hi, >> We are using Hbase batch API and with 0.98.1 we get the following exception >> on using batch() with Increment >> ———————————— >> org.apache.hadoop.hbase.exceptions.OperationConflictException: The operation >> with nonce {5266048044724982303, 5395957753774586342} on row >> [rowkey13-20140331] may have already completed >> at >> org.apache.hadoop.hbase.regionserver.HRegionServer.startNonceOperation(HRegionServer.java:4199) >> at >> org.apache.hadoop.hbase.regionserver.HRegionServer.increment(HRegionServer.java:4163) >> at >> org.apache.hadoop.hbase.regionserver.HRegionServer.doNonAtomicRegionMutation(HRegionServer.java:3424) >> at >> org.apache.hadoop.hbase.regionserver.HRegionServer.multi(HRegionServer.java:3359) >> at >> org.apache.hadoop.hbase.protobuf.generated.ClientProtos$ClientService$2.callBlockingMethod(ClientProtos.java:29503) >> at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2012) >> at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:98) >> at >> org.apache.hadoop.hbase.ipc.SimpleRpcScheduler.consumerLoop(SimpleRpcScheduler.java:160) >> at >> org.apache.hadoop.hbase.ipc.SimpleRpcScheduler.access$000(SimpleRpcScheduler.java:38) >> at >> org.apache.hadoop.hbase.ipc.SimpleRpcScheduler$1.run(SimpleRpcScheduler.java:110) >> at java.lang.Thread.run(Thread.java:745) >> ———————————— >> Eventually the job fails with >> "Error: org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException" >> >> The same job works in Hbase 0.94 installation.
