Brad Willard updated SPARK-11428:
---------------------------------
Description:
I have data being written into parquet format via spark streaming. The data can
change slightly so schema merging is required. I load a dataframe like this
{code}
urls = [
"/streaming/parquet/events/key=2015-10-30*",
"/streaming/parquet/events/key=2015-10-29*"
]
sdf = sql_context.read.option("mergeSchema", "true").parquet(*urls)
sdf.registerTempTable('events')
{code}
If I print the schema you can see the contested column
{code}
sdf.printSchema()
root
|-- _id: string (nullable = true)
...
|-- d__device_s: string (nullable = true)
|-- d__isActualPageLoad_s: string (nullable = true)
|-- d__landing_s: string (nullable = true)
|-- d__lang_s: string (nullable = true)
|-- d__os_s: string (nullable = true)
|-- d__performance_i: long (nullable = true)
|-- d__product_s: string (nullable = true)
|-- d__refer_s: string (nullable = true)
|-- d__rk_i: long (nullable = true)
|-- d__screen_s: string (nullable = true)
|-- d__submenuName_s: string (nullable = true)
{code}
The column that's in one but not the other file is d__product_s
So I'm able to run this query and it works fine.
{code}
sql_context.sql('''
select
distinct(d__product_s)
from
events
where
n = 'view'
''').collect()
[Row(d__product_s=u'website'),
Row(d__product_s=u'store'),
Row(d__product_s=None),
Row(d__product_s=u'page')]
{code}
However if I instead use that column in the where clause things break.
{code}
sql_context.sql('''
select
*
from
events
where
n = 'view' and d__product_s = 'page'
''').take(1)
