Missing -version

[CogumelosMaravilha]

Hi all,
With lots of virtualenvs and envs sometimes is difficult to know which version I'm using.
And most application have an -version option.
Can we have petrel -version?
Thanks.

Have you tried running "pip freeze"? I believe that'll tell you the versions of currently installed Python packages.

[barrywhart]

Or "pip show".

[CogumelosMaravilha]

Or pip list.
Yes I can type pip freeze|grep petrel or
petrel -version isn't this better?

[barrywhart]

I'll look into it at some point -- it shouldn't be much work. Just wanted to provide you an alternative for now.

Hi Barry,
Something is wrong with Petrel 1.0.1. I have a topology that runs ok on later version, and don't start at 1.0.1. Perhaps on Storm version 1.0.2 when you have a full patch version for the early problem, you can add the -v or -version. By the way how can I change the name of the GenericTopology?

[barrywhart]

What do you mean by "later version"? 1.0.1 is the latest.

Can you be more specific what you mean by changing the name?

[CogumelosMaravilha]

Sorry earlier version!
petrel submit --config topology.yaml --venv self --logdir pwd
I always get a GenericTopology on the jar file. I want to change the name.

[barrywhart]

The file it creates is called topology.jar. Do you mean you want to change the name of the file or the Java class? Why is this important/useful?

Maybe it will help me understand if you can fill in the blanks below:
As a ______, I want to ______ so that I can ____.

[barrywhart]

When you run on 1.0.1, do you get any errors, either written to the console or the logs? Have you tried running the word count sample? I tested with that before uploading the latest version to Pypi.

Can you please create separate tickets for your requests? We are discussing three different questions here:

• "-v" option
• Topology not working in 1.0.1
• Request for controlling topology name

[barrywhart]

BTW, you can specify the topology name on the Petrel command line. This is only applicable when submitting to a cluster, not when running in local mode. See the following code:

Hi Barry,
Lets see point by point. When I compile my topology for later submission;
petrel submit --config topology.yaml --venv self --logdir 'pwd'
$jar -xvf topology.jar |less
created: META-INF/
inflated: META-INF/MANIFEST.MF
created: storm/
created: storm/petrel/
inflated: storm/petrel/GenericTopology.class
I allway get a GenericTopology.class, and if I want to submit 2 topologies I cant because both have the same name. How can I change this name?

[CogumelosMaravilha]

Hi allways submit my topology like this;
storm jar topology.jar storm.petrel.GenericTopology Generic -c strom.petrel.GenericTopology Generic -c nimbus.host=127.0.0.1

[barrywhart]

Also, you were saying your topology won't start on 1.0.1. I asked some questions above about that.

[CogumelosMaravilha]

Hi Barry,
By mistake I was using my stom.yaml 0.1.0 on 1.0.1.
That's why topology never start and never log nothing! Solved.

[CogumelosMaravilha]

Today I saw the warning;
622 [main] WARN o.a.s.u.NimbusClient - Using deprecated config nimbus.host for backward compatibility. Please update your storm.yaml so it only has config nimbus.seeds

[barrywhart]

Cool, I'm glad you figured out the version issue. I created a new issue for the Storm setting: #78.
