Subject Re: disable spark disk cache
Date Mon, 04 Mar 2019 00:25:16 GMT
Hi Andrey,

Below is the description of MEMORY_ONLY from

"Store RDD as deserialized Java objects in the JVM. If the RDD does not fit
in memory, some partitions will not be cached and will be recomputed on the
fly each time they're needed. This is the default level."

Just curious how do you know Spark will be disk even option MEMORY_ONLY is
