[jira] [Created] (CASSANDRA-4058) Debian package does not create
/var/lib/cassandra/data
Debian package does not create /var/lib/cassandra/data
------------------------------------------------------
Key: CASSANDRA-4058
URL: https://issues.apache.org/jira/browse/CASSANDRA-4058
Project: Cassandra
Issue Type: Bug
Components: Packaging
Environment: Ubuntu 11.10
Reporter: Jacob Fenwick
I installed Cassandra using the Debian packages as described here: http://wiki.apache.org/cassandra/DebianPackaging
When trying to start Cassandra using /etc/init.d/cassandra start I get this error: java.io.IOError: java.io.IOException: unable to mkdirs /var/lib/cassandra/data
The directory /var/lib/cassandra exists, but the directory /var/lib/cassandra/data does not.
I would assume the data directory should have been created with the correct permissions, but it was not.
However, I tried creating /var/lib/cassandra/data and setting it the permissions to 666 and setting the user/group to cassandra/cassandra, and now I get this error:
java.lang.AssertionError: Directory /var/lib/cassandra/data is not accessible.
So what could possibly be the problem here?

Resolution: Not A Problem
I don't think papering over a problem a user has caused is a good idea, since they are possibly doing something they don't intend to.

not create /var/lib/cassandra/data

--------------------------------------------------------------------
Ok, admittedly, I think I may have already created those directories the first time I ran the package.
I tried installing the package on a different computer and it worked, setting the directories to the correct permissions.
However... I removed the package using apt-get remove, checked to see that /var/lib/cassandra was gone (which it was), removed /var/lib/cassandra (because it was still there), then reinstalled the package.
This time the directories had root as the owner.
How could the behavior change like that between two installs of the package?

[jira] [Commented] (CASSANDRA-4058) Debian package does not create

Jacob Fenwick commented on CASSANDRA-4058:
------------------------------------------
If you take the position that the users are required to set up data_file_directories, commitlog_directory, and saved_caches_directory manually, then yes it is a user caused problem as they didn't follow the documentation.
However, my observation is that a lot of packages make their default install have a basic working state that does not require additional system configuration.
If you look at a Debian package like MySQL, which also stores its data files in /var/lib by default, they use these sorts of permissions:
drwxr-s--- 2 mysql adm
I don't think it's unreasonable to set up permissions like that for the user automatically, but maybe there's something subtle about cassandra that I'm missing.

[jira] [Reopened] (CASSANDRA-4058) Debian package does not create
/var/lib/cassandra/data
Posted by "Jacob Fenwick (Reopened) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4058?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jacob Fenwick reopened CASSANDRA-4058:
--------------------------------------
I found a fix that works.
If you change the ownership of the directory /var/lib/cassandra to cassandra:
sudo chown -R cassandra:cassandra /var/lib/cassandra
Then Cassandra will be able to create the directories.
When installed from the Debian package, by default, /var/lib/cassandra has these permissions:
drwxr-xr-x 5 root root
So either the directory has to be set so users besides the owner can read and execute in the directory, or the user that cassandra uses needs to own the directory.
/var/log/cassandra also has this issue as the output.log complains that system.log can't be created.
That issue can be fixed by running:
sudo chown -R cassandra:cassandra /var/log/cassandra
Seems like it should be an easy fix in the Debian package. If you think this is the right fix and is worth fixing I can probably look at it.

Brandon Williams resolved CASSANDRA-4058.
-----------------------------------------
Resolution: Not A Problem
Cassandra itself will create this directory if it doesn't exist. You likely have a problem in a directory higher up in the hierarchy making it inaccessible.

Brandon Williams commented on CASSANDRA-4058:
---------------------------------------------
My point is that the 'cassandra' user's home directory is /var/lib/cassandra, so it should already own it when the package creates this user. If you ahead of time create this directory with the wrong permissions, that is your mistake to correct, not the package's to solve with brute force.
