hotdog updated SPARK-11101:
---------------------------
    Description: 
when using pipe() operation with large data(10TB), the pipe() operation always 
OOM. 
I use pipe() to calling a external c++ process. I'm sure the c++ program only 
use little memory(about 1MB).
my parameters:
executor-memory 16g
executor-cores 4
num-executors 400
"spark.yarn.executor.memoryOverhead", "8192"
partition number: 60000

does pipe() operation use many off-heap memory? 
the log is :
killed by YARN for exceeding memory limits. 24.4 GB of 24 GB physical memory 
used. Consider boosting spark.yarn.executor.memoryOverhead.

should I continue boosting spark.yarn.executor.memoryOverhead? Or there are 
some bugs in the pipe() operation?
