             Summary: Spark Job on YARN fails with executors "Slave registration failed"
                 Key: SPARK-22199
                 URL: https://issues.apache.org/jira/browse/SPARK-22199
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.6.3
            Reporter: Prabhu Joseph


Spark Job on YARN Failed with max executors Failed.

ApplicationMaster logs:
{code}
17/09/28 04:18:27 INFO ApplicationMaster: Unregistering ApplicationMaster with FAILED (diag message: Max number of executor failures (3) reached)
{code}

Checking the failed container logs shows "Slave registration failed: Duplicate executor ID" whereas the Driver logs shows it has removed those executors as they are idle for spark.dynamicAllocation.executorIdleTimeout

Executor Logs:
{code}
17/09/28 04:18:26 ERROR CoarseGrainedExecutorBackend: Slave registration failed: Duplicate executor ID: 122
{code}

Driver logs:
{code}
17/09/28 04:18:21 INFO ExecutorAllocationManager: Removing executor 122 because it has been idle for 60 seconds (new desired total will be 133)
{code}

There are two issues here:

1. Error Message in executor is misleading "Slave registration failed: Duplicate executor ID"  as the actual error is it was idle
2. The job failed as there are executors idle for spark.dynamicAllocation.executorIdleTimeout
