>
> When block locations are not available Impala works quite differently. E.g.
> it doesn't create TScanRanges in the Frontend, but generates them in the
> backend from TFileSplitGeneratorSpec objects.
> It is possible to disable block location information via core-site.xml:
> {noformat}
> <property>
> <name>impala.preload-block-locations-for-scheduling</name>
> <value>false</value>
> </property>
> {noformat}
>
> Executing a set of tests with disabled block locations could catch a few
> errors in time.
