Thanks Neha for your response.
Now I am calling it like:
List partitions = zkclient.readData("/brokers/topics/test-topic/1");
//topic = test topic and broker id is 1
*1. * Now _connection.readData(path, stat, watch); is returning a
byte[] of [49]. But derializable(data) is throwing ZkMarshallingError.
org.I0Itec.zkclient.exception.ZkMarshallingError: java.io.EOFException
at
org.I0Itec.zkclient.serialize.SerializableSerializer.deserialize(SerializableSerializer.java:37)
*2.* Apart from that byte 49 is number 1. But here my partition id is
0. Is derializable(data) suppose to convert [49] to [0] ?
Code snippet where it is failing.
Class ZkClient.java
protected T readData(final String path, final Stat
stat, final boolean watch) {
byte[] data = retryUntilConnected(new Callable() {
@Override
public byte[] call() throws Exception {
return _connection.readData(path, stat, watch);
}
});
return (T) derializable(data); //data here [49]. But derializable
throwing ZkMarshallingError
}
Please help.
Thanks
Sourabh
