Subject [jira] [Created] (SPARK-8702) Avoid massive concating strings in Javascript
Date Mon, 29 Jun 2015 10:58:05 GMT
Shixiong Zhu created SPARK-8702:
-----------------------------------

             Summary: Avoid massive concating strings in Javascript
                 Key: SPARK-8702
                 URL: https://issues.apache.org/jira/browse/SPARK-8702
             Project: Spark
          Issue Type: Sub-task
          Components: Web UI
            Reporter: Shixiong Zhu


When there are massive tasks, such as {{sc.parallelize(1 to 100000, 10000).count()}}, the
generated JS codes have a lot of string concatenations in the stage page, nearly 40 string
concatenations for one task.

We can generate the whole string for a task instead of execution string concatenations in
the browser.
