---------------------------------

             Summary: ApplicationMasterProtocolPBClientImpl.allocate fails with EOFException
when RPC privacy is enabled
                 Key: YARN-6013
                 URL: https://issues.apache.org/jira/browse/YARN-6013
             Project: Hadoop YARN
          Issue Type: Bug
          Components: client, yarn
    Affects Versions: 2.8.0
            Reporter: Steven Rand
            Priority: Critical


When privacy is enabled for RPC (hadoop.rpc.protection = privacy), {{ApplicationMasterProtocolPBClientImpl.allocate}}
sometimes (but not always) fails with an EOFException. I've reproduced this with Spark 2.0.2
built against latest branch-2.8 and with a simple distcp job on latest branch-2.8.

Steps to reproduce using distcp:

1. Set hadoop.rpc.protection equal to privacy
2. Write data to HDFS. I did this with Spark as follows: 

{code}
sc.parallelize(1 to (5*1024*1024)).map(k => Seq(k, org.apache.commons.lang.RandomStringUtils.random(1024,
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWxyZ0123456789")).mkString("|")).toDF().repartition(100).write.parquet("hdfs:///tmp/testData")
{code}

3. Attempt to distcp that data to another location in HDFS. For example:

{code}
hadoop distcp -Dmapreduce.framework.name=yarn hdfs:///tmp/testData hdfs:///tmp/testDataCopy
{code}

I observed this error in the ApplicationMaster's syslog:

{code}

Marking as "critical" since this blocks YARN users from encrypting RPC in their Hadoop clusters.
