--------------------------------

             Summary: Parquet files created in impala using data from hive tables resulted
in incorrect string representation
                 Key: DRILL-815
                 URL: https://issues.apache.org/jira/browse/DRILL-815
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Norris Lee


The parquet file was created by first loading a csv file into a hive table. A parquet table
was then created in impala and data from the hive table was loaded in. The file was extracted
from hdfs to local and placed into drill's dfs.
The keycolumn column in hive is of type string.
