@John D
@John D. As Divakar pointed out Hortonworks Products page is a great place to start. It has step by step tutorials and overall about the HDP. In general if you would like to learn Apache Hadoop is a good place http://hadoop.apache.org/. As for a book - http://www.amazon.com/Hadoop-Definitive-Guide-Tom-White/dp/1449311520 The above is a very good book. Hortonworks being part of the open source community and the only distribution with 100% open source projects. Hadoop has grown in many breadth and depths. Traditionally lot of work was done on map reduce and now people have moved more towards Hive (SQL Interface) and Spark. I would say if you are starting of as a developer, start with Spark. Also as you come from C#, picking up Scala will not be bad and you may enjoy working with Spark. Understanding Map Reduce framwork, HDFS and internals of Yarn is important to be skilled in Hadoop. I would say best of luck for your journey.

You cannot delete tags currently only remove tags from an entity. Delete functionality is not supported currently.

@Artem Ervits I have gone through the docs. Please see the comment to Neeraj's question. a) How do you set this in Ambari? The Hive Queues do not get set. Try this on Sandbox.

I have seen this before. screen-shot-2016-02-23-at-43742-am.png Ambari does not allow you to do this? Tried in sandbox Couple of other side affects a) If I set tez.queue.name explicitly Performance of queries of demo 2 is much slower b) Both the queues have 50% of the queue capacity

The default value is set to 10,000 and should be > 100, as per the docs. How should this value be changed or altered? Need some guidance. If I have a large table of billion rows should we increase the value? Will this be affected by? I am assuming also that the "orc.bloom.filter.columns" will be the list of columns on which the indexes will be created?

Is creating indexes on hive table recommended? http://www.slideshare.net/ye.mikez/hive-tuning?next_slideshow=1 It sort of suggests that creating indexing should be avoided. Just want some thought from the community on this.
