Subject Re: Spark Streaming: CoarseGrainedExecutorBackend: Slave registration failed: Duplicate executor ID
Date Tue, 16 Sep 2014 12:26:04 GMT
It seems that, as I have a single scala application, the scheduler is the
same and there is a collision between executors of both spark context. Is
there a way to change how the executor ID is generated (maybe an uuid
instead of a sequential number..?)
