Alessio updated SPARK-15904:
----------------------------
Description:
Running MLlib K-Means on a ~400MB dataset (12 partitions), persisted on Memory
and Disk.
Everything's fine, although at the end of K-Means, after the number of
iterations, the cost function value and the running time there's a nice
"Removing RDD <idx> from persistent list" stage. However, during this stage
there's a high memory pressure. Weird, since RDDs are about to be removed.
I'm running this cluster analysis on a 16GB machine, with Spark Context as
local[*]. My machine has an i5 hyperthreaded dual-core, thus [*] means 4.
I'm launching this application though spark-submit with --driver-memory 10G
