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

             Summary: YARN - Spark progress bar stucks at 10% but after 
finishing shows 100%
                 Key: SPARK-5925
                 URL: https://issues.apache.org/jira/browse/SPARK-5925
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.2.1
            Reporter: Laszlo Fesus
            Priority: Minor


I did set up a yarn cluster (CDH5) and spark (1.2.1), and also started Spark 
History Server. Now I am able to click on more details on yarn's web interface 
and get redirected to the appropriate spark logs during both job execution and 
also after the job has finished. 

My only concern is that while a spark job is being executed (either yarn-client 
or yarn-cluster), the progress bar stucks at 10% and doesn't increase as for 
MapReduce jobs. After finishing, it shows 100% properly, but we are loosing the 
real-time tracking capability of the status bar. 

Also tested yarn restful web interface, and it retrieves again 10% during 
(yarn) spark job execution, and works well again after finishing. (I suppose 
for the while being I should have a look on Spark Job Server and see if it's 
possible to track the job via its restful web interface.)

Did anyone else experience this behaviour? Thanks in advance.
