Let's start with Hive and then HCatalog. Hive
Layer for analyzing, querying and managing large datasets that reside in Hadoop various file systems ⇢ uses HiveQL (HQL) as processing engine ⇢ uses SerDes for serialization and deserialization ⇢ works best with huge volumes of data HCatalog
Table and storage management layer for Hadoop ⇢ basically, the EDW system for Hadoop (it supports several file formats such as RCFile, CSV, JSON, SequenceFile, ORC) ⇢ is a sub-component of Hive, which enables ETL processes ⇢ tool for accessing metadata that reside in Hive Metastore ⇢ acts as an API to expose the metastore as REST interface to external tools such as Pig ⇢ uses WebHcat, a web server for engaging with the Hive Metastore I think the focus has to be made on how they complement each other rather than focusing on their differences. Documentation (3)
This answer from @Scott Shaw is worth checking This slideshare presents the use cases and features of Hive and Hcatalog This direct graph from IBM shows how they use both layers in a batch job I hope this helps! 🙂

That was a smart move actually... imagine Samsung mobiles merging with Apple... 'D Good questions btw. We have to wait until Jan. 15 to take a deep-dive into new certifications. That would be great if they could come up with a "get 1 for 2!" (HortonWorks and Cloudera certification process). Fingers crossed!

Btw, they spam us with granular & top-notch resources. I think it worths the spam. ^.^
