FileNotFoundException on the checkpoints

[Guilherme Hott]

I'm having this error randomly if I change the name of the applications sometimes works some don't. Why causes this error?

java.lang.IllegalStateException: Deploy request failed: [OperatorDeployInfo[id=8,name=ConsoleJdbcError,type=GENERIC,checkpoint={ffffffffffffffff, 0, 0},inputs=[OperatorDeployInfo.InputDeployInfo[portName=input,streamId=Error JDBC Chains,sourceNodeId=6,sourcePortName=error,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>]],outputs=[]], OperatorDeployInfo[id=3,name=chainDedup,type=GENERIC,checkpoint={ffffffffffffffff, 0, 0},inputs=[OperatorDeployInfo.InputDeployInfo[portName=input,streamId=CloutAPI Affiliates POJO Stream,sourceNodeId=4,sourcePortName=outputPort,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>]],outputs=[OperatorDeployInfo.OutputDeployInfo[portName=unique,streamId=Unique Affiliates,bufferServer=<null>], OperatorDeployInfo.OutputDeployInfo[portName=duplicate,streamId=Duplicate Affiliates,bufferServer=<null>]]], OperatorDeployInfo[id=6,name=ChainJdbcOutputOperator,type=GENERIC,checkpoint={ffffffffffffffff, 0, 0},inputs=[OperatorDeployInfo.InputDeployInfo[portName=input,streamId=CloutAPI Chains POJO Stream,sourceNodeId=5,sourcePortName=outputPojo,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>]],outputs=[OperatorDeployInfo.OutputDeployInfo[portName=error,streamId=Error JDBC Chains,bufferServer=<null>]]], OperatorDeployInfo[id=2,name=cloutApiInputOperator,type=INPUT,checkpoint={ffffffffffffffff, 0, 0},inputs=[],outputs=[OperatorDeployInfo.OutputDeployInfo[portName=outputPort,streamId=CloutAPI Affiliates POJO Stream,bufferServer=<null>]]], OperatorDeployInfo[id=1,name=cloutApiInputOperator,type=INPUT,checkpoint={ffffffffffffffff, 0, 0},inputs=[],outputs=[OperatorDeployInfo.OutputDeployInfo[portName=outputPort,streamId=CloutAPI Affiliates POJO Stream,bufferServer=<null>]]], OperatorDeployInfo[id=5,name=LoadObject,type=GENERIC,checkpoint={ffffffffffffffff, 0, 0},inputs=[OperatorDeployInfo.InputDeployInfo[portName=input,streamId=Unique Affiliates,sourceNodeId=3,sourcePortName=unique,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>], OperatorDeployInfo.InputDeployInfo[portName=input2,streamId=Duplicate Affiliates,sourceNodeId=3,sourcePortName=duplicate,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>]],outputs=[OperatorDeployInfo.OutputDeployInfo[portName=outputPojo,streamId=CloutAPI Chains POJO Stream,bufferServer=<null>]]], OperatorDeployInfo[id=7,name=console,type=GENERIC,checkpoint={ffffffffffffffff, 0, 0},inputs=[OperatorDeployInfo.InputDeployInfo[portName=input,streamId=CloutAPI Chains POJO Stream,sourceNodeId=5,sourcePortName=outputPojo,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>]],outputs=[]], OperatorDeployInfo.UnifierDeployInfo[id=4,name=cloutApiInputOperator.outputPort#unifier,type=UNIFIER,checkpoint={ffffffffffffffff, 0, 0},inputs=[OperatorDeployInfo.InputDeployInfo[portName=<merge#outputPort>,streamId=CloutAPI Affiliates POJO Stream,sourceNodeId=1,sourcePortName=outputPort,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>], OperatorDeployInfo.InputDeployInfo[portName=<merge#outputPort>,streamId=CloutAPI Affiliates POJO Stream,sourceNodeId=2,sourcePortName=outputPort,locality=CONTAINER_LOCAL,partitionMask=0,partitionKeys=<null>]],outputs=[OperatorDeployInfo.OutputDeployInfo[portName=outputPort,streamId=CloutAPI Affiliates POJO Stream,bufferServer=<null>]]]]

What do you mean by "if I change the name of the applications"? Is that in the launch command or the ApplicationName annotation in Application.java? Are you sure there is any connection between this error and application name changing?

I mean this name here

I don't have sure if this is related to the error, but was the only thing I changed when I had this problem and worked. But this happens a lot, so maybe there is a way to fix this issue for good.
