CDH6 install requires additional /user/yarn directories to deploy

[brittup]

The CDH 6 installer will fail on the deployment of yarn as directories are missing under /user/yarn as it cannot deploy the mr-framework.tar.gz. It does not attempt to create them.

It requires the creation of the following directories under /user/yarn:

/user/yarn/mapreduce /user/yar/mapreduce/mr-framework

Adding manually and setting the permission on them on Isilon directly resolves this issue.

@brittup What steps you have done manually? Could you write them down here?

[brittup]

when fixing manually, I would just create the required missing directories:

cd to the Isilon access zone Hadoop root directory /user/yarn

create the two directories: mapreduce & mapreduce/mr-framework in the /user/yarn path

set the ownership on the new directories to yarn:yarn

eg: cd /ifs/cdh6/hadoop/hadoop-root/user/yarn

mkdir mapreduce mkdir mapreduce/mr-framework

chown -R yarn:yarn mapreduce

[tucked]

It does not attempt to create them.

Does this fail on a vanilla (i.e. non-OneFS) deploy too?

• If so, that seems like an upstream bug.
• If not, do we know why this is specific to OneFS?

edit: If the latter, maybe AMBARI-24893 is related?

I believe this is fixed now
