Riak Mesos 1.3 install – possible missing dependency?
ChiralMedia opened this issue · comments
After installing version 1.3 on DCOS 1.7 / Mesos 0.28.1 I get the following (config file attached)
The config has the latest versions of scheduler, executor and explorer.
[u1@bootstrapper riak-mesos]$ dcos package install riak --options /etc/riak-mesos/config.dcos.json
The Riak framework should have at least 1GB of RAM and 0.5 CPUs to perform successfully.
Continue installing? [yes/no] yes
Installing Marathon app for package [riak] version [1.3.0]
Installing CLI subcommand for package [riak] version [1.3.0]
New command available: dcos riak
Thank you for installing Riak on Mesos. Visit https://github.com/basho-labs/riak-mesos for usage information.
[u1@bootstrapper riak-mesos]$
[u1@bootstrapper riak-mesos]$ dcos riak

ImportError: cannot import name PIPE
Is there a dependancy missing that contains PIPE? There are a number of possible packages, but I don't want to be installing blind.
I just hit this exact problem myself last night.
It looks like something changed in dcos==0.4.12 that causes this. I'm looking into fixes/workarounds now.
The changes introduced between dcos==0.4.11 and dcos==0.4.12 made the library compatible only with python-3.4.x, according to the updated README:
dcos/dcos-cli@0.4.11...master#diff-88b99bb28683bd5b7e3a204826ead112R35
I'm going to push out a tweak to our CLI that locks us into dcos==0.4.11 for now, while we investigate longer-term solutions.
@ChiralMedia unrelated to this but possibly of interest to you: we have created a new version of the DC/OS packages, which gives you separate frameworks for running Riak KV and Riak TS in parallel within DC/OS.
If you wish to switch to it, you can do so by removing the repo that points to .../dcoscli-0.4.x.zip and replace it with one that points to .../develop.zip
This will give you 2 separate packages, riak-kv and riak-ts, which default to Riak KV 2.1.4 and Riak TS 1.3.1 respectively.
Meanwhile, I have merged the required changes into the DC/OS packages so if you try to reinstall now you should no longer have this problem.
I'll close this issue, but please feel free to re-open if these updates do not fix the problem for you!
That has fixed it, thanks.
