             Summary: Time elapsed per cell error
                 Key: ZEPPELIN-681
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-681
             Project: Zeppelin
          Issue Type: Bug
          Components: GUI
    Affects Versions: 0.5.6, 0.5.5
         Environment: Spark 1.6 (and Spark 1.5.2)
            Reporter: Joel Van Veluwen


Hey Guys, 
 
I’ve noticed that the time elapsed section at the end of a cell, the Took x seconds doesn’t always reconcile with the time elapsed in the application master of Spark – particularly when two cells are executed in sequence. 
 
I’m using Zeppelin 0.55 with Spark 1.5.2 and these errors are appearing on the Spark interpreter. 
 
It appears that the latest cell is bringing the sum of the previous cell into the execution time. An example is below where Cell 1 reconciles with Spark but the following cells add the previous time elapsed to their time taken.

Clearly Zeppelin needs to communicate with Spark and render the result - but an empty cell shouldn't take the same amount of time as the previous cell. It looks like there is a bug.
