Till Rohrmann updated FLINK-22597:
----------------------------------
Description: Since we are reusing the {{DefaultLeaderRetrievalService}} for
finding the resource manager in the {{JobMaster}} and since the leader
retrieval service cannot be reused, it is not possible to restart the
{{JobMaster}}. This causes Flink to fail in case that the {{JobMaster}} regains
the leadership in Flink versions <= 1.12. The problem no longer occurs for
newer versions because of FLINK-11719. (was: Since we are reusing the
{{DefaultLeaderRetrievalService}} for finding the resource manager in the
{{JobMaster}} and since the leader retrieval service cannot be reused, it is
not possible to restart the {{JobMaster}}. This causes Flink to fail in case
that the {{JobMaster}} regains the leadership in Flink versions <= 1.12.)
