Hi,
after some researches I found the problem, is related to the hadoop-common library 2.6.0 and Java 8.
Basically the function UGI#reloginFromKeytab inside the DataWriter.java class used to renew everyday the Kerberos ticket fail silently due to a parameter (isKeyTab) that returns false every time even if should be true (link bug: https://issues.apache.org/jira/browse/HADOOP-10786).
I solved the issue using Java 7 to run the connector and also with the usage of Hadoop-Clent 2.6.1 library that has the fix inside.
Regards,
Alex

@AlexPiermatteo Thank you for doing the research and providing the feedback. We will need to update the Hadoop version in future releases in order to support Java 8. Currently, our platform is Java 7 compliant.
