Subject Unable to connect to Spark thrift JDBC server with pluggable authentication
Date Fri, 17 Oct 2014 20:14:22 GMT
Hi,

if Spark thrift JDBC server is started with non-secure mode, it is working
fine. with a secured mode in case of pluggable authentication, I placed the
authentication class configuration in conf/hive-site.xml

 <property>
  <name>hive.server2.authentication</name>
  <value>CUSTOM</value>
 </property>
 <property>
  <name>hive.server2.custom.authentication.class</name>
 <value>org.apache.hive.service.auth.WebConsoleAuthenticationProviderImpl</value>
 </property>

and the jar containing the implementation is in Spark classpath, still
getting exception, it seems to me it couldn't find the authentication class
I specified in the configuration:

14/10/17 12:44:33 ERROR server.TThreadPoolServer: Error occurred during

why is that?

Thanks for your help!
