Find sample spark-default.conf as below. Replace the correct value for below markers:

<hadoop-client-native> : Dir path to hadoop native dir , In hdp clusters , it is generally /usr/hdp/current/hadoop-client/lib/native

<spark-history-dir> : HDFS dir on cluster where spark history server event log should be stored. Make sure this dir is owned by spark:hadoop with 777 permission

spark.driver.extraLibraryPath <hadoop-client-native>:<hadoop-client-native>/Linux-amd64-64
spark.eventLog.dir hdfs:///<spark-history-dir>
spark.eventLog.enabled true
spark.executor.extraLibraryPath <hadoop-client-native>:<hadoop-client-native>/Linux-amd64-64
spark.history.fs.logDirectory hdfs:///<spark-history-dir>
spark.history.provider org.apache.spark.deploy.history.FsHistoryProvider
spark.history.ui.port 18080
spark.yarn.containerLauncherMaxThreads 20
spark.yarn.driver.memoryOverhead 384
spark.yarn.executor.memoryOverhead 384
spark.yarn.historyServer.address xxx:18080
spark.yarn.preserve.staging.files false
spark.yarn.queue default
spark.yarn.scheduler.heartbeat.interval-ms 5000
spark.yarn.submit.file.replication 3

Find sample spark-env.sh as below. Please update the paths as per your environment.

export SPARK_CONF_DIR=/etc/spark/conf
export SPARK_LOG_DIR=/var/log/spark
export SPARK_PID_DIR=/var/run/spark
export HADOOP_HOME=${HADOOP_HOME:-/usr/hdp/current/hadoop-client}
export HADOOP_CONF_DIR=${HADOOP_CONF_DIR:-/usr/hdp/current/hadoop-client/conf}
# The java implementation to use.
export JAVA_HOME=<jdk path>

Hope this helps.
