Hmmm, Flink should not delete the stored blobs on the HA storage. Could you try to reproduce the problem and then send us the logs on DEBUG level? Please also check before shutting the cluster down, that the files were there.Cheers,TillOn Sun, Jun 3, 2018 at 1:10 PM miki haiat <miko5054@xxxxxxxxx> wrote:Hi Till ,
- the files are not longer exist in HDFS.
- yes , stop and start the cluster from the bin commands.
- unfortunately i deleted the log.. :(I wondered if this code could cause this issue , the way in using checkpointStateBackend sb = new FsStateBackend("hdfs://***/flink/my_city/checkpoints");
env.getCheckpointConfig().setCheckpointInterval(60000);On Fri, Jun 1, 2018 at 6:19 PM Till Rohrmann <trohrmann@xxxxxxxxxx> wrote:Hi Miki,could you check whether the files are really no longer stored on HDFS? How did you terminate the cluster? Simply calling `bin/stop-cluster.sh`? I just tried it locally and it could recover the job after calling `bin/start-cluster.sh` again.What would be helpful are the logs from the initial run of the job. So if you can reproduce the problem, then this log would be very helpful.Cheers,TillOn Thu, May 31, 2018 at 6:14 PM, miki haiat <miko5054@xxxxxxxxx> wrote:Hi,Im having some wierd issue with the JM recovery ,
