If historyserver.web.tmpdir is not set then java.io.tmpdir is used, so
that should be fine.
What are the contents of /local/scratch/flink_historyserver_tmpdir?
I assume there are already archives in HDFS?

My machine’s /tmp directory is not large enough to support the

historyserver.web.tmpdir, so I suspect it was still pointing at /tmp.
I just tried setting historyserver.web.tmpdir to the same location as
my java.io.tmpdir location, but I’m afraid I’m still seeing the
following issue:

Did you have anything else in mind when you said pointing somewhere funny?

overview.json is a generated file that is placed in the local
directory controlled by /historyserver.web.tmpdir/.
Have you configured this option to point to some non-local filesystem?
(Or if not, is the java.io.tmpdir property pointing somewhere funny?)

Hi Chesnay, thanks for responding. We’re using Flink 1.9.1. I
enabled DEBUG level logging and this is something relevant I see:

Aside from that, it looks like a lot of logging around datanodes
and block location metadata. Did I miss something in my classpath,
perhaps? If so, do you have a suggestion on what I could try?

Which Flink version are you using?
Have you checked the history server logs after enabling debug logging?

Hi,
I’m trying to set up the History Server, but none of my
applications are showing up in the Web UI. Looking at the
console, I see that all of the calls to /overview return the
following 404 response: {"errors":["File not found."]}.
I’ve set up my configuration as follows:
JobManager Archive directory:
*jobmanager.archive.fs.dir*:
hdfs:///user/p2epda/lake/delp_qa/flink_hs/
-bash-4.1$ hdfs dfs -ls /user/p2epda/lake/delp_qa/flink_hs

History Server will fetch the archived jobs from the same
location:
*historyserver.archive.fs.dir*:
hdfs:///user/p2epda/lake/delp_qa/flink_hs/
So I’m able to confirm that there are indeed archived
applications that I should be able to view in the histserver.
I’m not able to find out what file the overview service is
looking for from the repository – any suggestions as to what I
could look into next?
Best,
Andreas
