dsc12 on Debian Squeeze

[tommymcglynn]

Hello,

Trying to use this module but provision hangs when trying to install dsc12. I wasn't able to manually install dsc12 with apt-get or yum either.

Linux version 2.6.32-5-amd64 (Debian 2.6.32-48)

Thanks for your bug report.

Does the problem occur on a fresh install or on upgrading an existing DSC install?

I'm not aware of any (packaging) bug in DSC 1.2 on Debian Squeeze. Could you please try to run a manual installation of DSC 1.2 on a fresh Debian Squeeze system and check if there are any error messages?

[tommymcglynn]

Thank you for the follow up. This happens on a fresh install. If I don't include the cassandra module and try to install dsc12 directly, I get the following output

(I ran apt-get update before this)
vagrant@debian-squeeze:~$ sudo apt-get install dsc12
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package dsc12

Also, here is my simple manifest file https://gist.github.com/tommymcglynn/6a053ccd85e61384773e

Here is the vagrant log for where provisioning hangs:

I'm running into the same problem on fresh Ubuntu 12.04.2. Here's the trace from the install

err: /Stage[main]/Cassandra::Install/Package[dsc]/ensure: change from purged to present failed: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install dsc12' returned 100: Reading package lists...

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dsc12 : Depends: cassandra (= 1.2.9) but 2.0.0 is to be installed
E: Unable to correct problems, you have held broken packages.

I've recently experienced the same issue. I suppose that's because cassandra has been updated to 2.0.0 but the dsc12 (which have a dependency on cassandra) didn't have been updated with cassandra 2.0.0 but still need 1.2.9.

I use this little workaround which fit my needs :

class { 'cassandra':
    package_name => "cassandra",
    version => "1.2.9"
    [...]
}

Regards,

Matt

edit : the problem could maybe be fixed by changing the apt policy of the package 1.2.9. I didn't try this...

[timfallmk]

As a follow up to @msimonin workaround, you can specify the variables $cassandra_version, and $cassandra_package_name in your ENC (or however you're doing it) to the values he gave above.

Another quick way of fixing this issue is to replace all "dsc12" occurrences with "dsc20" occurrences in the modules directory. This way you'll be able to install the latest (2+) Cassandra version.

So, after installing the puppet module go to the modules/cassandra directory and run this command:

find . -type f -print0 | xargs -0 sed -i 's/dsc12/dsc20/g'

IMO this may be the way to fix the bug too.

Cheers!

Why not?

class { 'cassandra':
    package_name => "dsc20",
    [...]
}

FYI. This is what I'm currently doing for cassandra 1.2. You need to install the dsc12 package or an apt-get upgrade will upgrade to version 2.x.

package { "dsc12":
    ensure => present,
    require => Package['cassandra'],
}
class { 'cassandra':
  cluster_name        => 'dit',
  seeds               => [ '10.0.0.12', '10.0.0.13', '10.0.0.14', ],
  package_name        => 'cassandra',
  version             => '1.2.15',
  # thread_stack_size => '256',
}

For Cassandra 2.0, I use the patch posted in issue #14 and on some JVM's I need to increase the thread_stack_size.

class { 'cassandra':
  cluster_name        => 'v2Cluster',
  seeds               => [ '10.0.0.17', '10.0.0.18', '10.0.0.21', ],
  package_name        => 'dsc20',
  thread_stack_size   => '256',
}
