Hi Chesnay, yes – they were created using Flink 1.9.1 as we’ve only
just started to archive them in the past couple weeks. Could you
clarify on how you want to try local filesystem archives? As in
changing jobmanager.archive.fs.dir and historyserver.web.tmpdir to the
same local directory?

hmm...let's see if I can reproduce the issue locally.
Are the archives from the same version the history server runs on?
(Which I supposed would be 1.9.1?)
Just for the sake of narrowing things down, it would also be
interesting to check if it works with the archives residing in the
local filesystem.

There are just two directories in here. I don’t see cache
directories from my attempts today, which is interesting. Looking
a little deeper into them:
bash-4.1$ ls -lr

There are indeed archives already in HDFS – I’ve included some in
my initial mail, but here they are again just for reference:

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

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

Did you have anything else in mind when you said pointing

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*:

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
