|
Use the <codeph>ALLOW_ERASURE_CODED_FILES</codeph> query option to enable or disable the
|
|
support of erasure coded files in Impala. Until Impala is fully tested and certified with
|
|
erasure coded files, this query option is set to <codeph>FALSE</codeph> by default.
|
|
</p>
|
|
|
|
<p>
|
|
When the <codeph>ALLOW_ERASURE_CODED_FILES</codeph> query option is set to
|
|
<codeph>FALSE</codeph>, Impala returns an error when a query requires scanning an erasure
|
|
coded file.
