Cheng Hao created SPARK-4856:
--------------------------------
Summary: Null & empty string should not be considered as
StringType at begining in Json schema inferring
Key: SPARK-4856
URL: https://issues.apache.org/jira/browse/SPARK-4856
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Cheng Hao
We have data like:
{panel}
TestSQLContext.sparkContext.parallelize(
"""{"ip":"27.31.100.29","headers":{"Host":"1.abc.com","Charset":"UTF-8"}}""" ::
"""{"ip":"27.31.100.29","headers":{}}""" ::
"""{"ip":"27.31.100.29","headers":""}""" :: Nil)
{panel}
As empty string will be considered as String in the beginning (in line 2 and
3), it ignores the real nested data type (struct type in line 1), and also take
the line 1 (the "headers") as String Type.
