Subject [jira] [Updated] (PIG-1914) Support load/store JSON data in Pig
Date Fri, 28 Sep 2012 17:01:09 GMT

     [ https://issues.apache.org/jira/browse/PIG-1914?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dmitriy V. Ryaboy updated PIG-1914:
-----------------------------------

    Status: Open  (was: Patch Available)

canceling patch status, pending review response.

please note that in the mean time, JsonStorage/Loader were added to Pig, but they are bound
to a strict schema and the loader essentially only works on json stored by JsonStorage, not
any json.  So we probably still need an alternative loader.

Also note that EB is now much more modular (so, fewer dependencies required if you do not
need them), and the json storage module there allows deep parsing (tuples, maps, the works).
It does not sample any records to auto-determine schema, and still returns a map.

> The JSON is a commonly used data storage format. It is popular for storing structured
data, especially for JavaScript data exchange. 
> Pig should have the ability to load/store JSON format data. I plan to write one for the
piggy bank.
