He Xiaoqiao commented on HDFS-12733:
------------------------------------
[~shv], Thanks for your suggestions.
{quote}I would really prefer if this could be done without introducing new
config parameters.
HDFS-14511 shows how it can and is done in current implementation with existing
configuration options. We should clearly document this.{quote}
I agree with you one hundred percent. As HDFS-14511 mentioned, I do not find
any use case of local edit in HA mode. So in my opinion, I agree that we should
do not load {{dfs.namenode.edits.dir}} anymore in HA mode if we has config
{{dfs.namenode.shared.edits.dir}} item.
But of course, we should toward agreement, [~elgoiri] any other concerns?
Thanks again.

> Disabling local edits gives little performance improvement.
