James Maki commented on SPARK-20530:
------------------------------------
As with SPARK-17100 calling {{cache()}} allows this filter to work, but it
doesn't seem like that should be necessary.
Additionally, some other operations (like calling {{distinct()}} after the
filter can also allow this flow to work.
> "Cannot evaluate expression" when filtering on parquet partition column
> -----------------------------------------------------------------------
>
> Key: SPARK-20530
> URL: https://issues.apache.org/jira/browse/SPARK-20530
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 2.1.0
> Environment: spark-2.1.0-bin-hadoop2.7.tgz Python2
> Reporter: James Maki
>
> In pyspark, when filtering on a parquet partition column, the following error
> occurs:
> {code}
> py4j.protocol.Py4JJavaError: An error occurred while calling o54.toString.
> : java.lang.UnsupportedOperationException: Cannot evaluate expression:
> <lambda>(input[0, int, true])
> {code}
> Reproduce via the following script:
> {code}
> from pyspark.sql import SparkSession
> from pyspark.sql.functions import udf
> from pyspark.sql.types import BooleanType
> if __name__ == '__main__':
> sql = SparkSession.builder.getOrCreate()
> data = [(0, 1), (0, 2), (0, 3), (1, 4), (1, 5), (1, 6)]
> sql.createDataFrame(data, ['key', 'value'])\
> .write\
> .partitionBy('key')\
> .format('parquet')\
> .save('dest.parquet', mode='overwrite')
> sql.read.parquet('dest.parquet')\
> .filter(udf(lambda x: True, BooleanType())('key'))\
> .explain(extended=True)
> {code}
> Full script output
> {code}
