Apache Drill Impersonation -

-

i'm trying build in security on our drill (1.6.0) system. managed security user authentication work(jpam explained in documentation), impersonation not seem work. seems execute , fetch via the admin user regardless of has logged in via odbc.

my drill-override.conf file configured follows:

  drill.exec: {   cluster-id: "drillbits1",   zk.connect: "localhost:2181",   impersonation: {     enabled: true,     max_chained_user_hops: 3   },   security.user.auth {       enabled: true,       packages += "org.apache.drill.exec.rpc.user.security",       impl: "pam",       pam_profiles: [ "sudo", "login" ]     } }

we using drill on 1 server, therefore i'm running drill-embedded start things up. troubleshooting:
