Oozie warden.ooziee.conf not placed in correct location while installing Mapr packages

[Vipul Nayyar]

In the configuration phase of a Mapr 5.0.0 CentOS cluster in Openstack Liberty 3.0.2, warden fails to start oozie with the following error:

Error during operating on cluster (reason: RemoteCommandException: Error during command execution: "sudo -u mapr maprcli node services -name oozie -action start -nodes 11.11.11.8"
ERROR (10002) - Service: oozie is not configured on node:

The reason for this is that after oozie rpm packages are installed, the warden.oozie.conf file originally present in /opt/mapr/oozie/oozie-4.1.0/conf is not copied to the location /opt/mapr/conf/conf.d where other warden process config files are stored.

Is it reproducible on the latest master code? I think that we can't backport that to stable/liberty because it's now open for security fixes and for critical bugs.

With 5.1.0 plugin

I'll try to test this on the latest master code, but I wanted this bug filed here for posterity as this is not documented.

For the config I used : Centos Mapr 5.0.0 on Openstack Liberty 3.0.2, I edited the sahara pre-built image with guestfish tool and added the warden.ooziee.conf originally present in /opt/mapr/oozie/oozie-4.1.0/conf to /opt/mapr/conf/conf.d directory. Then uploaded the edited image again to glance and booted the cluster after registering it with Mapr plugin again.

Hope this helps someone !!

It has to be reproducible only on Liberty and earlier versions. The root cause is that MapR plugin creates mapr user after oozie instalation. After Liberty release mapr-oozie-4.2 was released and in 4.2 they changed the instalation process that it requires mapr user to be created before oozie install, they also backported this change into mapr-oozie 4.1, so it broke the configuration. This is not the only issue that comes from backporing changes into old version of mapr-ecosystem. In hive 1.0 they changed property name, so, most likely, hive is broken too.

Thanks Grigory. I think it ok now to Invalidate bug.
