This means > that both the ODBC and JDBC drivers as well as the web/REST interfaces should > support inbound Kerberos. For Web this would most likely be SPNEGO while for > ODBC and JDBC this will be more generic Kerberos. > Since Hive and much of Hadoop supports Kerberos there is a potential for a > lot of reuse of ideas if not implementation. > Note that this is related to but not the same as > https://issues.apache.org/jira/browse/DRILL-3584 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
