yangwwei commented on issue #92: fix a scheduler deadlock 
URL: https://github.com/apache/incubator-yunikorn-core/pull/92#issuecomment-592706379
 
 
   Since we are using the fine-grained locking mechanism, I am suggesting to fix this issue
with the changes in this PR. The idea is to avoid calling `sa.updateAskRepeatInternal()` in
`recoverOnNode()`. I was first trying to move the app lock inside of  `updateAskRepeatInternal()`
but that doesn't work because this "internal" call is assumed to be app-lock-free.
