["John Sirois (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AURORA-1672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15250611#comment-15250611 ] 

John Sirois commented on AURORA-1672:
-------------------------------------

The only obvious bug in that RB is the {{populateDiscoveryInfo}} field being added to {{ExecutorSettings}} but not being incorporated in the {{hashCode}} or {{equals}} implementations: https://github.com/apache/aurora/commit/915459dac76ed0732addce87420a4ba51d916de8#diff-f5ae46f7a3e0af5901caa0e0ed17cdb3R34

> While working on the unified containerizer support, I noticed that I was seeing duplicate task events in the scheduler UI. On digging further, these events were present in the DB as well. Initially I thought it was related to the storage changes for task images, but I was able to reproduce on a sha before those changes were introduced.
> I ran a git bisect to see what commit introduced this bug and it pointed to: https://github.com/apache/aurora/commit/915459dac76ed0732addce87420a4ba51d916de8
> It's not immediately obvious to me how that change is causing this, especially since setting {{-populate_discovery_info=false}} in {{aurora-scheduler.conf}} does *not* fix the problem.
