Subject [jira] [Commented] (SPARK-18352) Parse normal, multi-line JSON files (not just JSON Lines)
Date Fri, 18 Nov 2016 02:36:58 GMT

    [ https://issues.apache.org/jira/browse/SPARK-18352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15675517#comment-15675517

Reynold Xin commented on SPARK-18352:
-------------------------------------

Actually just talked to [~marmbrus] and now I understand more how JSON reader works.

I'd say we always turn the top level array into multiple records, and then have only one option:
wholeFile. This same option can be used in json and text.

> Spark currently can only parse JSON files that are JSON lines, i.e. each record has an
entire line and records are separated by new line. In reality, a lot of users want to use
Spark to parse actual JSON files, and are surprised to learn that it doesn't do that.
> We can introduce a new mode (wholeJsonFile?) in which we don't split the files, and rather
stream through them to parse the JSON files.
