Question

GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos credentails)

livy 0.7.1 CDH 6.3.2(enable kerberos)

in livy.conf

livy.server.auth.type = kerberos
livy.server.auth.kerberos.principal = jzyc/[email protected]
livy.server.auth.kerberos.keytab = /hadoop/app/jzyc_bigdser4.keytab
livy.server.launch.kerberos.keytab = /hadoop/app/HTTP.keytab
livy.server.launch.kerberos.principal = HTTP/[email protected]
livy.impersonation.enabled = false

1.admin.local -q "addprinc jzyc/bigdser4" 2. kadmin.local -q "xst -k jzyc_bigdser4.keytab jzyc/[email protected]"

I can run livy,but I can't use livy. I get error"GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos credentails)"

in logs I can see

21/04/21 17:24:35 INFO LivyServer: SPNEGO auth enabled (principal = jzyc/[email protected])

# livy.server.auth.type = kerberos
# livy.server.auth.kerberos.principal = jzyc/[email protected]
# livy.server.auth.kerberos.keytab = /hadoop/app/jzyc_bigdser4.keytab
 livy.server.launch.kerberos.keytab = /hadoop/app/jztwk.keytab
 livy.server.launch.kerberos.principal = jztwk/[email protected]
 livy.impersonation.enabled = true
