> It's a bit unclear are both, SPARK_HOME and HADOOP_HOME are required to
use this mode or only SPARK_HOME should be enough.
It depends on spark distribution.
If system provided spark is "pre-build with user-provided Hadoop", then
both SPARK_HOME and HADOOP_HOME is required. Otherwise, only SPARK_HOME would
be enough.
