Use the <codeph>DEFAULT_FILE_FORMAT</codeph> query option to set the default table file
|
|
format. The following values are supported:
|
|
</p>
|
|
|
|
<p>
|
|
<ul>
|
|
<li>
|
|
<codeph>TEXT</codeph> (<codeph>0</codeph>)
|
|
</li>
|
|
|
|
<li>
|
|
<codeph>RC_FILE</codeph> (<codeph>1</codeph>)
|
|
</li>
|
|
|
|
<li>
|
|
<codeph>SEQUENCE_FILE</codeph> (<codeph>2</codeph>)
|
|
</li>
|
|
|
|
<li>
|
|
<codeph>AVRO</codeph> (<codeph>3</codeph>)
|
|
</li>
|
|
|
|
<li>
|
|
<codeph>PARQUET</codeph> (<codeph>4</codeph>)
|
|
</li>
|
|
|
|
<li>
|
|
<codeph>KUDU</codeph> (<codeph>5</codeph>)
|
|
</li>
|
|
|
|
<li>
|
|
<codeph>ORC</codeph> (<codeph>6</codeph>)
|
|
</li>
|
|
</ul>
|
|
</p>
|
|
|
|
<p>
|
|
In impala-shell or Hue, the <codeph>SET DEFAULT_FILE_FORMAT</codeph> statement will not
|
|
return an error when the option was set to an unsupported value. Impala validates the
|
|
value and returns an error when you submitted the next query.
