Optimal size of the Impala Scratch directory -


scratch directory size small (there 4 directories set - 1 per node). cloudera support got rid of 1 of them, unclear if right configuration.

how decide optimal size of impala scratch directory?

so run df -h figure out how available space have, , make sure impala-scratch directory isn't larger that.
