> In this issue we have a long running Spark application with secure HBase, which requires {{HBaseCredentialProvider}} to get tokens periodically, we specify HBase related jars with {{\--packages}}, but these dependencies are not added into AM classpath, so when {{HBaseCredentialProvider}} tries to initialize HBase connections to get tokens, it will be failed.
> Currently because jars specified with {{\--jars}} or {{\--packages}} are not added into AM classpath, the only way to extend AM classpath is to use "spark.driver.extraClassPath" which supposed to be used in yarn cluster mode.
> So here we should figure out a solution  either to put these dependencies to AM classpath or to extend AM classpath with correct configuration.
