[jira] [Commented] (HDFS-15659) Set
dfs.namenode.redundancy.considerLoad to false in MiniDFSCluster
[ https://issues.apache.org/jira/browse/HDFS-15659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17222090#comment-17222090 ]
Ayush Saxena commented on HDFS-15659:
-------------------------------------
[~aajisaka] IIRC couple of days back you had objections having this config disabled in a test. I didn't follow up, and I lost the track of that Jira too. Is that concern not there now?
I think there the number of datanodes were increased instead? If we are doing this, I don't think that fix would be required? So, If this concludes, We can revert that. Increasing datanodes has adverse affect on test performance, though minor

> dfs.namenode.redundancy.considerLoad is true by default and it is causing many test failures. Let's disable it in MiniDFSCluster.

> i've certain seen this option causing test failures in the past.
> Maybe we should turn it off by default in MiniDDFSCluster, and only enable it for specific tests.
