I have now completed the DFHz Hue Management Pack which you can now use to install Hue 3 or Hue 4 in HDP 2 or HDP3.   Just be careful in selecting your correct version(s) and getting the correct mpack install command.  They are each very specific. Check out the repo:   https://github.com/steven-dfheinz/dfhz_hue_mpack     ... View more

@bhara This morning I did a 3 node HDP 2.6.5 cluster with NameNode HA (the point you had conflict in).   The install worked from management pack without issues.  Hue install and started.    No problems.   In my early morning testing,  I had installed Hue before doing NameNode HA.  So for the HA test, I stopped hue, executed 2 rms below, deleted service from ambari, and did a re-install from ambari.      14  rm -rf /usr/local/hue    15  rm -rf /usr/hdp/current/hue-server   If you continue to have issues, you will need to debug using method I showed you before:  edit the files that are throwing errors.   Looking at the conflicts, and commenting/debugging python is how I even got this to work at all.   In my original article I discuss some important information about debugging the service files directly, and using the retry button during the install or start section of the Ambari Add Service Wizard.      If you do find a solution that needs to be changed, please report it back so that I can get the repo updated.   I am doing an update now to include the rms above, making an install/reinstall from ambari easier.   ...

@Former Member here is an article that explains how to use variables:   https://community.cloudera.com/t5/Community-Articles/Introduction-into-Process-Group-Variables/ta-p/247625   You should create important variables at the main root canvas level for all your NiFi environments.  Then access these variables within your NiFi Registry controlled process groups via variable syntax: ${variableName}.   Then when you import that to another environment the variables already exist and the flow works after importing.     ...

I will check again in the morning. Some of what you are seeing now is that the original Ambari hue service wasn’t finished for high availability. This is a customer service so... The last changes I suggest are to get around those settings manually. High Availability and SSL is on my list of things to do but so far I have been very busy just getting the base of this all working with single node cluster. I will run a multi node cluster in the morning and update repo. ... View more

@bhara  Install completed, that's some good progress!   Congrats.   Your start error is saying problem with: Execution of '/var/lib/ambari-agent/cache/common-services/HUE/4.6.0/package/files/configs.sh set catl0dlbd00028.corp.cox.com HDP_ANALYTICS_DEV httpfs-site 'httpfs.proxyuser.hue.groups' '*'' returned 1.

@bhara you should be good to do a full reset and re-install and it should work.   Make sure you follow all the commands for reset.   If it fails again its going to be from previous attempts (not removing all parts) or dependency (should be resolved).   HDP 2.6.5 Hue 4.6.0 Management pack worked for me today:   ambari-server install-mpack --mpack=https://github.com/steven-dfheinz/dfhz_hue_mpack/raw/master/hue_mpack-4.6.0-0.0.tar.gz --verbose ambari-server restart  https://github.com/steven-dfheinz/dfhz_hue_mpack ...

@bhara In a previous post you got past the "Hue Service is installed" step, which means all dependencies must have not caused any errors in "make install".     Your last reply is an error in make install.    Maybe you can just try again and see if that resolves it.   Also make sure you have package npm and maven.   If you are stuck in install attempt,  you can also manually go to the node and finish the install:   rm -rf /usr/local/hue cd /usr/local/hue-4.6.0  PREFIX=/usr/local/ make install Let this run and see if it finishes.   It is sometimes necessary to do the manual install and resolve the issues for dependency or to at least know confidently the make install works.    If it does work, the dependencies are good.   After this manual test, the next thing to do is a full reset  from ambari and try all over again.   Full reset is: Stop Service in Ambari Delete Service Execute the rm commands rm -rf /var/lib/ambari-server/resources/stacks/HDP/2.6/services/HUE rm -rf /var/lib/ambari-agent/cache/stacks/HDP/2.6/services/HUE/ rm -rf /usr/local/hue rm -rf /usr/hdp/current/hue-server rm -rf /usr/local/hue-* Re-install Custom Hue Service or Install Management Pack Restart Ambari Attempt fresh install ...
