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
