[jira] [Updated] (FLINK-28130) FLIP-224: Blocklist Mechanism

     [ https://issues.apache.org/jira/browse/FLINK-28130?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lijie Wang updated FLINK-28130:
-------------------------------
    Description: 
In order to support speculative execution for batch jobs([FLIP-168|https://cwiki.apache.org/confluence/display/FLINK/FLIP-168%3A+Speculative+Execution+for+Batch+Job]), we need a mechanism to block resources on nodes where the slow tasks are located. We propose to introduce a blocklist mechanism as follows:  Once a node is marked as blocked, future slots should not be allocated from the blocked node, but the slots that are already allocated will not be affected.

More details see [FLIP-224|https://cwiki.apache.org/confluence/display/FLINK/FLIP-224%3A+Blocklist+Mechanism]
