Why RDD is not cached?

Hi,

I have a standalone spark , where the executor is set to have 6.3 G memory
, as I am using two workers so in total there 12.6 G memory and 4 cores.

I am trying to cache a RDD with approximate size of 3.2 G, but apparently
it is not cached as neither I can see  "  BlockManagerMasterActor: Added
rdd_XX in memory " nor  the performance of running the tasks is improved

But, why it is not cached when there is enough memory storage?
I tried with smaller RDDs. 1 or 2 G and it works, at least I could see
"BlockManagerMasterActor:
Added rdd_0_1 in memory" and improvement in results.

Any idea what I am missing in my settings, or... ?

thanks,
/Shahab

Did you intend to mail the Apache Spark mailing list, instead of the Apache
Cassandra User mailing list?
