Hi,
I am using EMR 4.7 with Spark 1.6 
Sometimes when I start the spark shell I get below error 

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005662c0000, 10632822784, 0) failed; error='Cannot allocate memory' (errno=12)

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 10632822784 bytes for committing reserved memory.
# An error report file with more information is saved as:

Has any body encountered this kind of issue .
Would really appreciate the resolution.


Thanks,
