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. Any tips on which config settings to play with to resolve this? Is the application supposed to handle these exceptions? (something new in Hbase 0.98 or 0.96 ??) Thanks, -Vinay
