Can a docker image use hadoop?

Cannot access HDFS from MapR Data Science Refinery docker container

QUESTION

Can a docker image use hadoop?

Asked 2019-Sep-03 at 20:23

Can a docker image access hadoop resources? Eg. submit YARN jobs and access HDFS; something like MapR's Datasci. Refinery, but for Hortonworks HDP 3.1. (May assume that the image will be launched on a hadoop cluster node).

Saw the hadoop docs for launching docker applications from hadoop nodes, but was interested in whether could go the "other way" (ie. being able to start a docker image with the conventional docker -ti ... command and have that application be able to run hadoop jars etc. (assuming that the docker image host is a hadoop node itself)). I understand that MapR hadoop has docker images for doing this, but am interested in using Hortonworks HDP 3.1. Ultimately trying to run h2o hadoop in a docker container.

Anyone know if this is possible or can confirm that this is not possible?

Yes. As long as you have the client jars and appropriate configs similar to an edge node for your container it should work.

Cannot access HDFS from MapR Data Science Refinery docker container

Asked 2018-Dec-28 at 01:47

Trying to follow this article (https://mapr.com/blog/how-to-run-data-science-refinery-from-an-edge-node/) for setting up DSR docker image (tag: v1.1_6.0.0_4.1.0_centos7) on an edge node (see here for how to set some of the env.list values: https://mapr.com/docs/61/AdvancedInstallation/Env_Variables_Installer_Container.html). However, once the container is started,

The DSR image seems to have a bug where, even though the mapr SASL ticket specified in the env.list file exists and is valid, it is not getting copied to the container when it is started. Thus, the container can't connect to the MapR HDFS. To fix this, did...

Created a file of the same name as the ticket file in the same location on the container as specified in the env.list value specifying where the ticketfile would be
Manually copy-pasted the contents of the ticketfile from the host to the ticket file we just created in the docker container
(After waiting a bit (~2 minutes)) Restarted the mapr posix service: sudo service mapr-posix-client-container restart

After doing this, the container appears to be able to access the HDFS (and submit YARN jobs) fine.

(If anyone has any more information on why this could be happening or if there is a better workaround to get the container working as expected, please let me know).
