com.hazelcast.nio.serialization.HazelcastSerializationException: info.jerrinot.subzero.relocated.com.esotericsoftware.kryo.KryoException: Buffer underflow

jerrinot commented 7 years ago

@mukul4u2005: can you describe your setup a bit? do you have a reproducer?

mukul4u2005 commented 7 years ago

I am using subzero-all-0.6 jar , It is working fine on my local machine but when I am deploying on production the deserialization is not working , The serialization is not giving any issue but when I am doing get operation on Map in hazelcast it is throwing this exception .

jerrinot commented 7 years ago

do you have subzero registered on all members and clients?

mukul4u2005 commented 7 years ago

I am deploying hazelcast as embeded of war file and doing programmatic configuration as:

SubZero.useForClasses(config, ActionLogDetails.class, ActionLogResponse.class, ServerDetails.class);

So there are two tomcat instance and making cluster there. Some time i got same exception like during migration and not I am getting this exception when I am doing get operation on Map.

jerrinot commented 7 years ago

can you post a full stacktrace?

any chance you could share your domain classes? you can obfustate them, but it's hard to tell anything from the log.

public class AllocationDetails {

private List<AllocationInstance> allocationInstanceList;
private String atype;
private String aid;

jerrinot commented 7 years ago

can you try to create a reproducer? if there is a serialization issue then it should be possible to create a local reproducer - just start multiple Hazelcast instances in a single JVM.

mukul4u2005 commented 7 years ago

hmmm I will try to create but I found on kryo website support some people facing similar exception because they did not have output.flush(); after writeObject method.

@Override public void write(ObjectDataOutput out, Test object) throws IOException { Output output = new Output((OutputStream) out); getKryo().writeObject(output, object); output.flush();

}

Is that can be reason. Mean in Subzero we have to mention sumwhere

jerrinot commented 7 years ago

SubZero calls the flush, see https://github.com/jerrinot/subzero/blob/5f80142d77e4ba1759f71c9fe0b5fde7623ada8b/subzero-core/src/main/java/info/jerrinot/subzero/internal/strategy/KryoStrategy.java#L70

mukul4u2005 commented 7 years ago

Ok I am trying to reproduce but for your information there are some exception in log files showing during replication as:

An exception occurred while executing migration operation com.hazelcast.map.impl.operation.MapReplicationOperation{serviceName='hz:impl:mapService', identityHash=270795521, partitionId=0, replicaIndex=0, callId=0, invocationTime=-1 (1970-01-01 00:59:59.999), waitTimeout=-1, callTimeout=9223372036854775807} com.hazelcast.nio.serialization.HazelcastSerializationException: info.jerrinot.subzero.relocated.com.esotericsoftware.kryo.KryoException: Buffer underflow.

jerrinot commented 7 years ago

@mukul4u2005: hi, do you have any uppdate/reproducer?

mukul4u2005 commented 7 years ago

@jerrinot: Hi, That I tried to reproduce on my local it is working fine but it is failing in INT environment with same implementation. SO I am not sure what is happening.
