[GitHub] [incubator-uniffle] zuston commented on pull request #192: [ISSUE-186][Feature] Use I/O cost time to select storage paths

zuston commented on PR #192:
URL: https://github.com/apache/incubator-uniffle/pull/192#issuecomment-1231906496

   Before reviewing this PR, I have some questions
   1. How to disable this strategy in conf? If we only specify one path, there is no need to do storage selection, like specifying single s3a path.
   2. IO cost time maybe meaningless depending on the single w/r      time to construct the rank. But I think it’s ok to check whether the dfs namespace is healthy by this way
   3. Can u share some requirements on your production env. From my side, dfs can be as a big and stable enough store for storing shuffle data.
