---------------------------------
Summary: Presto plugin lookupResource throws NPE if not set
service password
Key: RANGER-2944
URL: https://issues.apache.org/jira/browse/RANGER-2944
Project: Ranger
Issue Type: Bug
Components: plugins
Reporter: Jiayi Liu
In the configuration of Ranger Presto plugin service, password is not a
required content. Only when SSL is enabled in Presto, we need to fill in the
password. When Presto does not enable SSL, if you fill in the password when
configuring the service, the connection will fail and an exception will be
thrown.
{code:java}
java.sql.SQLException: Authentication using username/password requires SSL to
be enabled
{code}
However, currently in the code, we always put
{{prop.getProperty(HadoopConfigHolder.RANGER_LOGIN_PASSWORD)}} to
prestoProperties, if the password is not set,
{{prop.getProperty(HadoopConfigHolder.RANGER_LOGIN_PASSWORD)}} will be null. If
we put a null value to {{Properties}}, this will throw NPE. We need to check
whether we have set the password.
