Known Issues

• Issue with Pig Config (do not use pig HDP 3.x )
• If Hbase or Spark are missing, the install will fail on missing config objects
• Some params are hardcoded for single node test
• Not tested SSL & High Availability
• There could still be conflicts with config params not yet migrated to HDP 3.x format -- Conflict with Spark2 config object -- Conflict with Hbase Thrift Server v1
• Very long compile time as "make apps" takes nearly 30 minutes to complete dependencies
• hue user, hue group error when Ambari is Managing User/Group Creation. The work around is below:

python /var/lib/ambari-server/resources/scripts/configs.py -u admin -p admin -n HDP3 -l hdp3.cloudera.com -t 8080 -a set -c cluster-env -k  ignore_groupsusers_create -v true

**** make sure to get correct Cluster Name (HDP3) and Ambari Host (hdp3.cloudera.com) for command above

Coming Soon

• Create a repository for hue fileset built via "make apps"
• WIP - Updates for Hue 4.x - Hue.4.6.0 Branch
• WIP - Bundling this service into an easier to use Management Pack - dfhz_hue_mpack
• Add better handling for missing components and/or multi-node clusters
• Improve functionality for SSL and High Availability
• Resolve User KeyError (python work around above)
