We are using mapr 6.0.0 cluster which is having a support of drill 1.11.0. We have launched drill on yarn on mapr cluster successfully with PAM authentication enabled. But whenever we try to connect from client machine, it throws an error saying Could not get JDBC Connection; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!.
On disabling the PAM authentication, everything works fine. Is PAM authentication not supported with drill 1.11.0? Please note that we have disabled client to drillbit encryption and drillbit to drillbit encryption in both cases.
