I decided to transition to shared profile locations for my drill cluster. I
updated the drill-override.conf with a blobroot setting
sys.store.provider.zk.blobroot: "maprfs:///tmp/drill/profiles”
and made sure the directory existed with permissions for everyone.
I restarted the drill-bits and ran a few queries. All was wonderful … all 9
nodes saw the same profiles.
I then copied the earlier profiles from
/opt/mapr/drill/drill-1.1.0/logs/profiles on all the cluster nodes to that
maprfs:/// <maprfs:///> location. But those profiles did not show up. I
restarted the services … no change. The profiles generated post changing
drill override.conf were still visible; the others were not.
Any thoughts as to the reason for this behavior ? Is there some way to
“register” the earlier profiles with the drill cluster ?
