Subject [jira] [Updated] (FALCON-1096) Scan Hive Metastore to automatically create Falcon feeds for existing Hive tables
Date Sat, 14 Mar 2015 21:32:38 GMT

     [ https://issues.apache.org/jira/browse/FALCON-1096?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adam Kawa updated FALCON-1096:
------------------------------
    Description: 
In my organisation we create a Hive table for each production dataset in HDFS. When creating
a Hive table, you supply a lot of information about your dataset: its name, fields and their
types and comments, the location, the data format, properties in form of the key-value pairs
and meaningful description of the dataset. We think of Hive as a central and nicely documented
repository of our datasets.

When using Falcon, we again need to create Falcon feed for each dataset (that corresponds
to a Hive table) and even specify multiple redundant properties (e.g. description).

To make it simpler, Falcon could scan the Hive Metastore and automatically create feeds for
each Hive table and inherit its properties.

The properties of Hive tables could be also used when searching for a dataset using new Falcon
Web UI e.g. field name, field comment, file format (some other statistics like total file
size, the last modification or access time could be also used).
