Subject [jira] [Created] (HADOOP-7833) Inner classes of org.apache.hadoop.ipc.protobuf.HadoopRpcProtos generates findbugs warnings which results in -1 for findbugs

Inner classes of org.apache.hadoop.ipc.protobuf.HadoopRpcProtos generates findbugs warnings
which results in -1 for findbugs
----------------------------------------------------------------------------------------------------------------------------

                 Key: HADOOP-7833
                 URL: https://issues.apache.org/jira/browse/HADOOP-7833
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: John Lee
            Priority: Blocker


findbugs reports the following medium priority warnings for some inner class in the generated
class ./hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/protobuf/HadoopRpcProtos.java:

* SE_BAD_FIELD_STORE: Non-serializable value stored into instance field of a serializable
class
* SE_BAD_FIELD: Non-transient non-serializable instance field in serializable class
* UCF_USELESS_CONTROL_FLOW: Useless control flow

This can be fixed by adding the following findbugs exclude filter:

+    <Match>
+      <!-- protobuf generated code -->
+      <Class name="~org\.apache\.hadoop\.ipc\.protobuf\.HadoopRpcProtos.*"/>
+    </Match>

which will exclude all inner classes of org.apache.hadoop.ipc.protobuf.HadoopRpcProtos
