Subject [jira] [Commented] (HIVE-16635) Progressbar: Use a step-function for CHECK_INTERVAL timeouts
Date Wed, 10 May 2017 22:20:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16005551#comment-16005551

Siddharth Seth commented on HIVE-16635:
---------------------------------------

+1. Couple of minor nits.
- 2.5s is pretty high, and will affect usability of the UI. Can this be lowered, maybe in
combination with TEZ-3719.
- {code}final int maxFailures = (MAX_RETRY_INTERVAL/MAX_CHECK_INTERVAL)+1;{code}
This may as well be a private static final.

> Fewer getProgress() calls can speed up Tez by ~20% - see TEZ-3719 for other half of this
improvement.
