             Summary: Cannot project all columns from a parquet files with ~1,100 columns
                 Key: SPARK-14223
                 URL: https://issues.apache.org/jira/browse/SPARK-14223
             Project: Spark
          Issue Type: Bug
            Reporter: Hossein Falaki


The parquet file is generated by saving first 10 rows of the 1000 genomes dataset. When I try to run "select * from" a temp table created from the file I get following error:

{code}
