<indexterm audience="hidden">PARQUET_FALLBACK_SCHEMA_RESOLUTION query option</indexterm>
- Allows Impala to look up columns within Parquet files by column name, rather than column order,
+ The <codeph>PARQUET_FALLBACK_SCHEMA_RESOLUTION</codeph> query option allows Impala to look
+ up columns within Parquet files by column name, rather than column order,
when necessary.
+ The allowed values are:
+ <ul>
+ <li>
+ POSITION (0)
+ </li>
+ <li>
+ NAME (1)
+ </li>
+ </ul>

<p>
By default, Impala looks up columns within a Parquet file based on
the order of columns in the table.
- The <codeph>name</codeph> setting for this option enables behavior for Impala queries
- similar to the Hive setting <codeph>parquet.column.index.access=false</codeph>.
+ The <codeph>name</codeph> setting for this option enables behavior for

It also allows Impala to query Parquet files created by Hive with the
<codeph>parquet.column.index.access=false</codeph> setting in effect.
