hansonhe updated FLINK-33481:
-----------------------------
Description:
FlinkVersion: 1.13.5 ,
(1) flink-conf.yaml
high-availability.zookeeper.path.root /flink
high-availability.zookeeper.quorum xxxxx
(2) jobmanager
application_1684323088373_1744
appattempt_1684323088373_1744_000001 Tue Oct 31 11:19:07 +0800 2023
appattempt_1684323088373_1744_000002 Sat Nov 4 11:10:52 +0800 2023
(3) When appattempt_1684323088373_1744_000001 failures, I found
3.1）Completed checkpoint 5750 for job 6262e8c6a072027459f9b4eeb3e9735c
stored on hdfs is successful
3.2) checkpoint stored in zookeper: /flink/application_1684323088373_1744
was deleted
the logs as following:
!image-2023-11-08-10-05-54-694.png!
!image-2023-11-08-09-40-59-889.png!
(4) After appattempt_1684323088373_1744_000001 failures, jobmanager switch to
start appattempt_1684323088373_1744_000002, the logs start as following: No
checkpoint found during restore !image-2023-11-08-09-57-17-739.png!
（5）My Question ：
5.1）Why were checkpoints stored on zookeeper deleted when JobManager
failures with Flink High Availability on yarn？It cause that Jobmanager run to
restore without checkpoint found
5.2）Why not use successful and completed checkpoint-5750 stored on
hdfs to restore when running jobmanager appattempt_1684323088373_1744_000002?
