Impala scratch file

Impala scratch file

Explorer
Hi,

I couldn't find any documentation about limiting scratch file.
Can anyone point me if it's possible?
What happens when I run out of free space ?

Best regards,

Morbious

Hi Morbious,
Currently Impala does not support limiting scratch file usage in this
way. You can achieve this at the operating system level with disk quotas
for the impala user or by putting the scratch directory on a separate disk
partition.

Tim

Hi Tim,

 

Thank you for answer.

What happens when space on the disk ends ?

If you run out of space the spilling query that hits the error will be
canceled and its disk space will be reclaimed.
