Command failed after 1 tries

I have noticed that hosts with Oozie Server and Clients do not have the following directories:

/usr/hdp/current/oozie-client/doc/
/usr/hdp/current/oozie-server/doc/

So, I have tried removing tsflags=nodocs from /etc/yum.conf and attempted reinstalling the oozie client, however, it still does not create the above folders.

@Dinesh Chitlangia

On the host where you are seeing the issue, try removing the rpm's of oozie using yum remove oozie_2_6_* and then try reinstalling it from the command line using the command yum install oozie_2_6_*

Please modify below script on ambari-server and replace cached copy of the same script with the modified script on each ambari-agent ( where you have oozie clients installed )

Script to be modified on Ambari Server:

/var/lib/ambari-server/resources/common-services/OOZIE/4.0.0.2.0/package/scripts/service_check.py

What to modify?

Add below line:

from resource_management import *

Where is cached copy on ambari-agents/oozie-clients?

/var/lib/ambari-agent/cache/common-services/OOZIE/4.0.0.2.0/package/scripts/service_check.py

After this, you may face below error:

resource_management.core.exceptions.Fail: Cannot find /usr/hdp/current/oozie-client/doc. Possible reason is that /etc/yum.conf contains tsflags=nodocs which prevents this folder from being installed along with oozie-client package. If this is the case, please fix /etc/yum.conf and re-install the package.

To fix this,

Edit /etc/yum.conf and remove/comment out

tsflag=nodocs

Run below commands to reinstall oozie packages.

yum reinstall -y oozie_2_6_*

Hope this helps! 🙂

@Kuldeep Kulkarni

Thanks that got me past the initial problem and then I ran into following error:

resource_management.core.exceptions.Fail: Cannot find /usr/hdp/current/oozie-client/doc. Possible reason is that /etc/yum.conf contains tsflags=nodocs which prevents this folder from being installed along with oozie-client package. If this is the case, please fix /etc/yum.conf and re-install the package.

This was resolved by @Mahesh Balakrishnan's input of remove and install the packages.
