Spark-shell->Insufficient memory for the Java Runtime Environment to continue

Hi ,

I am unable to start my spark-shell . I get the following error message . Kindly advice.
Insufficient memory for the Java Runtime Environment to continue

SPARK_MAJOR_VERSION is set to 1, using Spark
Java HotSpot™ 64-Bit Server VM warning: INFO: os::commit_memory(0x0000781344400000, 716177408, 0) failed; error=‘Cannot allocate memory’ (errno=12)

regards,
Sapna

I also not able to start spark. I am getting below error

Launch Spark using
Spark-shell – conf “Spark.ui.port=10101”
