[jira] [Commented] (FLINK-19853) BulkSlotProviderImplTest.testFailedBulkSlotAllocationReleasesAllocatedSlot failed in azure

    [ https://issues.apache.org/jira/browse/FLINK-19853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17224519#comment-17224519 ] 

Zhu Zhu commented on FLINK-19853:
---------------------------------

The failure cause is the concurrency of the released slot check and the slot releasing, because the pending logical slot allocation futures will be canceled before releasing the physical slot. So it is a test issue.
One way to fix the test case is to wait for the physical slots to be released within a period instead immediately check it is released.
However, given that {{BulkSlotProviderImpl}} is no longer used after we have {{SlotSharingExecutionSlotAllocator}}. I think we can simply remove it along with its tests.
