Juan Yu created HDFS-8409:
-----------------------------

             Summary: HDFS client RPC call throws "java.lang.IllegalStateException"
                 Key: HDFS-8409
                 URL: https://issues.apache.org/jira/browse/HDFS-8409
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
            Reporter: Juan Yu


When the HDFS client RPC calls need to retry, it sometimes throws "java.lang.IllegalStateException" and retry is aborted and cause the client call will fail.

{code}
Caused by: java.lang.IllegalStateException

Here is the check that throws exception
{code}
  public static void setCallIdAndRetryCount(int cid, int rc) {
      ...
      Preconditions.checkState(callId.get() == null);
  }
{code}

The RetryInvocationHandler tries to call it with not null callId and causes exception.
