Subject [jira] [Commented] (YARN-4837) User facing aspects of 'AM blacklisting' feature need fixing
Date Mon, 16 May 2016 04:20:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-4837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15284126#comment-15284126

Rohith Sharma K S commented on YARN-4837:
-----------------------------------------

Thanks [~vinodkv] for working on the patch!!.  Overall approach reasonable to me, and going
through patch more on depth. 
One suggestion is can default value for threshold reduce to less than 50%? May be reasonable
value is 20% or 10% so that probability of occurring issues like YARN-4685 can be reduced.

{code}
public static final float DEFAULT_AM_SCHEDULING_NODE_BLACKLISTING_DISABLE_THRESHOLD =
0.8f;
{code}

> Was reviewing the user-facing aspects that we are releasing as part of 2.8.0.
> Looking at the 'AM blacklisting feature', I see several things to be fixed before we
release it in 2.8.0.
