@Anandha L Ranganathan Every distribution of HDP is created and tested so that components are compatible with each other. So, if you want to upgrade all components in Ambari other than Kafka, while it is definitely possible, we don't recommend it for supportability and compatibility. Essentially, if you go this route, you are trying to create a distro of your own which won't be worth the pain due to possible unknown BUGs, support issues and other challenges. Better take your time, upgrade Dev cluster, re-write consumer jobs and then upgrade prod once you have tested everything. This would ensure smooth upgrade. Else time and effort saved here can result into pain in other areas down the road as mentioned above. Hope it helps!! ... View more

Got the solution after working with support. This is BUG in current Ambari and HDP versions. https://hortonworks.jira.com/browse/BUG-38390 Below is workaround: Change Log directory for Ranger Admin logs On Ranger Admin nodes: ADMIN LOGS (Change the symbolic link for in ews directory): mkdir /opt/hadoop/log/ranger/admin chmod 775 /opt/hadoop/log/ranger/admin chown ranger_qa:ranger_qa_grp /opt/hadoop/log/ranger/admin cd /usr/hdp/current/ranger-admin/ews unlink logs ln -s /opt/hadoop/log/ranger/admin logs From Ambari Web UI --> Change Log directory for Ranger Admin and restart Ranger. Note: here ranger_qa and ranger_qa_grp are ranger user and group respectively which are customized in my case. Change log directory for USERSYNC LOGS On Ranger Usersync node: mkdir /opt/hadoop/log/ranger/usersync chmod 775 /opt/hadoop/log/ranger/usersync chown ranger_qa:ranger_qa_grp /opt/hadoop/log/ranger/usersync Note: here ranger_qa and ranger_qa_grp are ranger user and group respectively which are customized in my case. 1. Make a back of file /usr/hdp/current/ranger-usersync/ranger-usersync-services.sh 2. Change the file to the path to your new log location. logdir=/var/log/ranger/usersync cd /usr/hdp/current/ranger-usersync/ cp ranger-usersync-services.sh{,.backup01122015} vi ranger-usersync-services.sh #logdir=/var/log/ranger/usersync logdir=/opt/hadoop/log/ranger/usersync From Ambari Web UI --> Change Log directory for Ranger Usersync and restart Ranger ...
