      Description

      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:

      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")
      

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

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

      I observed this error in the ApplicationMaster's syslog:

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