Turning on predicate pushdown for ORC datasources results in a
NoSuchElementException:
scala> val df = sqlContext.sql("SELECT name FROM people WHERE age < 15")
df: org.apache.spark.sql.DataFrame = [name: string]
scala> sqlContext.setConf("spark.sql.orc.filterPushdown", "*true*")
scala> df.explain
== Physical Plan ==
*java.util.NoSuchElementException*
Disabling the pushdown makes things work again:
scala> sqlContext.setConf("spark.sql.orc.filterPushdown", "*false*")
scala> df.explain
== Physical Plan ==
Project [name#6]
Filter (age#7 < 15)
Scan
OrcRelation[file:/home/mydir/spark-1.5.0-SNAPSHOT/test/people][name#6,age#7]
Have any of you run into this problem before? Is a fix available?
Thanks,
Ravi
