| <conbody> |
| |
| <p> |
| 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. |
