Cache directory not created exception

[FrEaKmAn]

Hi

I have 0.9.4 installed. I checkout develop branch and run it. It fails to run and gives me the following error

Deleting the /tmp/kairos_cache solves the problem, but is this normal?

[brianhks]

Iv'e seen this happen if Kairos was ran as root and then ran as another user it doesn't have access to the folder. Could this have been the case?

[FrEaKmAn]

Yes, you are correct. Do you think it would be better to run KairosDB under a special user instead of root?

[brianhks]

Yes we have an issue open to do just that.

Hi, I am sorry I am reviving an old thread, but I get the same error and in my case a kairos_cache folder is not present in the /tmp/ directory..I am using kairos 0.9.4 with cassandra. I have changed the permissions of /tmp/ folder to user instead of root, still i get the same error.

[brianhks]

And what happens if you use a different folder for the cache? Use something besides tmp use the users home folder.

[kabirbansod]

There was something in the settings that was trying to use SSL to establish connection with cassandra, and it was failing because i had not provisioned use of SSL, so i was getting that error, i am sorry. It is working fine now.

[brianhks]

No worries.

Hi

I just ran into a similar issue with the latest KairosDB version (1.1.1): despite having the kairosdb.query_cache.cache_dir set to /var/cache/kairosdb and running the kairosdb service with user kairosdb (at systemd service unit level), KairosDB still creates a directory in /tmp/kairosdb_cache.

Is the kairosdb.query_cache.cache_dir setting of any use in this case?

EDIT: actually it looks like KairosDB creates temporary directories in both kairosdb.query_cache.cache_dir and /tmp/kairosdb_cache...
