I am trying to run Spark using yarn and I am running into this error:

Exception in thread "main" java.lang.Exception: When running with master 'yarn' either HADOOP_CONF_DIR or YARN_CONF_DIR must be set in the environment.

I am not sure where the "environment" is (what specific file?). I tried using:

export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop

in the bash_profile, but this doesn't seem to help.

apache-spark hadoop

just an update to answer by Shubhangi,

 cd $SPARK_HOME/bin
 sudo nano load-spark-env.sh

add below lines , save and exit

export SPARK_LOCAL_IP="127.0.0.1"

export HADOOP_CONF_DIR="$HADOOP_HOME/etc/hadoop"

export YARN_CONF_DIR="$HADOOP_HOME/etc/hadoop"
