Re: [DISCUSS] official docker image(s) for hadoop

2017-09-22 Thread Marton, Elek 

Thanks all the feedbacks.

I created an issue:
https://issues.apache.org/jira/browse/HADOOP-14898

Let's continue the discussion there.

Thanks,

For testing and voting, I have been using docker containers for a while, see 
code at: https://github.com/weiqingy/caochong

I’m +1 on this idea. The “official” docker image basically means a commitment 
to maintain well documented and broadly tested images, which seems not a burden 
to us.

Ceph has a community docker project https://github.com/ceph/ceph-docker 
 and I think our scope here is similar to 
it.

It would be very helpful for testing the RC. To vote a RC, committers and
PMCs usually spend lots of time to compile, deploy the RC, do several

+1 (non-binding)
It would be really nice to have Docker to try different features of Hadoop 
(like HA, Federation Enabled, Erasure coding…), which will helpful for both 
developers and users.


Thanks,
Bharat

+1 definitely think an official Hadoop docker image (possibly 1 per major
or minor release) would be a positive both for contributors and for users
of Hadoop.

[DISCUSS] official docker image(s) for hadoop

2017-09-08 Thread Marton, Elek 


TL;DR: I propose to create official hadoop images and upload them to the 
dockerhub.


GOAL/SCOPE: I would like improve the existing documentation with 
easy-to-use docker based recipes to start hadoop clusters with various 
configuration.


The images also could be used to test experimental features. For example 
ozone could be tested easily with these compose file and configuration:


https://gist.github.com/elek/1676a97b98f4ba561c9f51fce2ab2ea6

Or even the configuration could be included in the compose file:

https://github.com/elek/hadoop/blob/docker-2.8.0/example/docker-compose.yaml

I would like to create separated example compose files for federation, 
ha, metrics usage, etc. to make it easier to try out and understand the 
features.


CONTEXT: There is an existing Jira 
https://issues.apache.org/jira/browse/HADOOP-13397
But it’s about a tool to generate production quality docker images 
(multiple types, in a flexible way). If no objections, I will create a
