As I mentioned I had given ownership to cassandra user for the
cassandra.pid containing folder, var/lib/cassandra & /var/log/cassandra.
All of them are owned by cassandra as I verified.
However after suggestion by someone, I tried removing the
folders var/lib/cassandra & /var/log/cassandra & restarted cassandra &
it seems to work fine now.. after this I can start the cassandra as a
service using
* sudo service cassandra start*
& can also see status using
*sudo service cassandra startus*
*
*
However is this a practical approach? should I just delete the entire
folders as such & let cassandra create new folders ? Wouldn't that
reduce some information from cassandra? (like the opscenter keyspaces
which were there by default but wont be created by cassandra itself ? or
anything else I dont know!).
However this means that folder permissions is not somehow correct, isn;t
it ? Shouldn't dsc installer be taking care of configuring this properly
? Or is it my responsibility ?
You shouldn't have needed to set any permissions - the package is
responsible for that. You shouldn't need to remove/remake directories.
It should "Just Work".
I went through a scratch install of dsc20 on an Ubuntu LTS machine to
see what the problem might be and attached the console log. I did find a
bug with the same behavior you described. I have no idea why someone
*removed* the dependency on a functional JRE from the cassandra package
- this is *not* the same Depends: line as the upstream OSS cassandra
package [0]. (You can see this in 'apt-cache show cassandra=2.0.5' as in
my console output.)
Did you discover your problem with using 'service cassandra
{start,status}' *before* you installed a JRE? I did.
As soon as I installed openjdk-7-jdk, the cassandra service start/status
"Just Worked", as I would expect.
I do see in the documentation, that the prerequisite lists "Java is
installed." [1] - in my opinion, it should be installed via package
dependency, just as the upstream package does. I will try to follow up
on this bug.
I appreciate your dilligence and verifying as best you can. Clear
reproduction steps, commands run, output text, etc., as I'm attaching,
is super helpful, for future reference :)
