I move the /tmp off local disk into the distributed FS on a node local volume
on MapR. Other file systems can be inserted.
Open up drill-override.conf on all of the nodes, and insert this :
sort: {
purge.threshold : 100,
external: {
batch.size : 4000,
spill: {
batch.size : 4000,
group.size : 100,
threshold : 200,
directories : [ "/var/mapr/local/Hostname/drillspill" ],
fs : "maprfs:///"
}
}
}
