[jira] [Commented] (SPARK-2010) Support for nested data in PySpark SQL

["Nicholas Chammas (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-2010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14085743#comment-14085743 ] 

Nicholas Chammas commented on SPARK-2010:
-----------------------------------------

I just tried this on {{master}}:

{code}
>>> from pyspark.sql import SQLContext
>>> sqlContext = SQLContext(sc)
>>> a = sc.parallelize([{'d': 4}, {'d': 10}])
>>> sqlContext.inferSchema(a)
.../python/pyspark/sql.py:1017: UserWarning: Using RDD of dict to inferSchema is deprecated
  warnings.warn("Using RDD of dict to inferSchema is deprecated")
MapPartitionsRDD[9] at mapPartitions at SchemaRDD.scala:408
{code}

Is this warning a hint at the work described in this JIRA issue? If so, what is the new way of converting an RDD of Python dictionaries to a SchemaRDD?
