java.lang.UnsupportedOperationException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • protobuf 2.5 is a bit faster with a new Parse to avoid a builder step and a few other goodies that we'd like to take advantage of over in hbase especially now we are all pb all the time. Unfortunately the protoc generated files are no longer compatible w/ 2.4.1 generated files. Hadoop uses 2.4.1 pb. This latter fact makes it so we cannot upgrade until hadoop does. This issue suggests hadoop2 move to protobuf 2.5. I can do the patch no prob. if there is interest. (When we upgraded our build broke with complaints like the below: {code} java.lang.UnsupportedOperationException: This is supposed to be overridden by subclasses. at com.google.protobuf.GeneratedMessage.getUnknownFields(GeneratedMessage.java:180) at org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos$GetDatanodeReportRequestProto.getSerializedSize(ClientNamenodeProtocolProtos.java:21566) at com.google.protobuf.AbstractMessageLite.toByteString(AbstractMessageLite.java:49) at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.constructRpcRequest(ProtobufRpcEngine.java:149) at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:193) at com.sun.proxy.$Proxy14.getDatanodeReport(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:164) at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:83) at com.sun.proxy.$Proxy14.getDatanodeReport(Unknown Source) at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getDatanodeReport(ClientNamenodeProtocolTranslatorPB.java:488) at org.apache.hadoop.hdfs.DFSClient.datanodeReport(DFSClient.java:1887) at org.apache.hadoop.hdfs.MiniDFSCluster.waitActive(MiniDFSCluster.java:1798 ... {code} More over in HBASE-8165 if interested.

  • I ran the full build in hadoop-1 profile, but it looks like the protobuf upgrade broke the hadoop-2 profile.
