Hi,
I have been unable to get proxyUsers to work with Livy. I seem to have
Kerberos configured correctly, as evidenced by the last beeline command. When
I start a livy session the server log will usually say something like: “owner:
kylo, proxyUser: Some(dladmin)” so it seems the server should know what to do.
But no matter what I try I always get “org.apache.spark.sql.AnalysisException:
Table not found”
