Cheng Lian updated SPARK-1913:
------------------------------
Description:
When scanning Parquet tables, attributes referenced only in predicates that are
pushed down are not passed to the `ParquetTableScan` operator and causes
exception. Verified in the {{sbt hive/console}}:
{code}
loadTestTable("src")
table("src").saveAsParquetFile("src.parquet")
parquetFile("src.parquet").registerAsTable("src_parquet")
hql("SELECT value FROM src_parquet WHERE key < 10").collect().foreach(println)
{code}
