Satish Subhashrao Saley commented on OOZIE-2658:
------------------------------------------------

{code}
private static final String DRIVER_CLASSPATH_OPTION = "--driver-class-path=";
{code}
You need to remove the {{=}} at the end of string. User would mention this option without {{=}} sign. Option and its value will be separated by space.
{code}
<spark-opts> --driver-class-path /some/path</spark-opts>
{code}

> In SparkMain we use the option {{--conf spark.driver.extraClassPath=}} to put together the jars needed for Spark. If the user specifies this option, Oozie appends to the value.
> If {{--driver-class-path}} is defined in {{<spark-opts>}} then it's value overwrites the other ones, causing the Spark action to fail.
> We should handle both ways to define classpaths the same.
