             Summary: History UI: Taking over 1 minute for initial page display
                 Key: SPARK-21254
                 URL: https://issues.apache.org/jira/browse/SPARK-21254
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 2.1.0
            Reporter: Dmitry Parfenchik


Currently on the first page load (if there is no limit set) the whole jobs execution history is loaded since the begging of the time, which in itself is not a big issue and only causes a small latency in case of 10k+ rows returned from the server. The problem is that UI spends most of the time processing the results even according to chrome devtools (newtwork IO is taking less than 1s):

In case of larger amount of rows returned (10k+) this time grows dramatically, causing 1min+ page load in Chrome and in Firefox, Safari and IE freezes the process.
