Have you followed all requirements for install? Firewall, NTP, selinux, transparent huge pages? Also, please look at Ambari Views as Hue replacement on HDP. It's pretty good option as compared to Hue.

have you seen this https://community.hortonworks.com/content/repo/4538/hdp-mongo-tutorial.html ? Also mongo driver is now at 1.4.2, it may be worth your time to use latest jar. https://github.com/mongodb/mongo-hadoop/releases

you also invested time in learning nifi, nifi has a cron based scheduler, would be interesting to see it leveraged for this use case. Look under scheduling tab https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#Configuring_a_Processor

You're custom paths don't look right, please look at sandbox pig configuration and try to identify inconsistencies
