Shuffle uses Direct Memory Buffer even after setting
"spark.shuffle.io.preferDirectBufs = false"
Hi,
I am using Standalone Spark 2.3 and have a question regarding Shuffle.
Going by the documentation, default Shuffle behaviour is to use Direct
Memory buffers. But, even after I set the following parameter, I notice
Shuffle still uses Direct Memory buffers.
spark.shuffle.io.preferDirectBufs = false
Is this a bug ? How can I disable use of Direct Memory for Shuffle
Thanks,
