pyspark资源配置
pyhton中，想像scala一样，对spark使用资源做指定，如：
spark-submit \
--principal $principal \
--keytab $keytab \
--name Test \
--master yarn --deploy-mode cluster \
--num-executors 10 \
--executor-cores 4 \
--executor-memory 16G \
--driver-memory 16G \
--conf spark.locality.wait=10 \
--conf spark.serializer="org.apache.spark.serializer.KryoSerializer" \
--conf spark.streaming.backpressure.enabled=true \
--conf spark.task.maxFailures=8 \
--conf spark.driver.maxResultSize=8G \
--conf spark.default.parallelism=500 \
--conf spark.sql.shuffle.partitions=300 \
--conf spark.sql.autoBroadcastJoinThreshold=-1 \
--conf spark.sql.broadcastTimeout=3000 \
--conf spark.yarn.submit.waitAppCompletion=true \
--conf spark.yarn.report.interval=6000 \
--conf spark.driver.extraClassPath=$localroot/config \
--conf spark.executor.userClassPathFirst=true \
--conf spark.hbase.obtainToken.enabled=true \
--conf spark.yarn.security.credentials.hbase.enabled=true \
--conf spark.executor.extraJavaOptions="${executorJavaOpts:34}" \
--conf spark.yarn.cluster.driver.extraJavaOptions="${driverJavaOpts:45}" \
--conf spark.driver.userClassPathFirst=true \
--conf spark.yarn.dist.innerfiles=$SPARK_HOME/conf/log4j-executor.properties,$SPARK_HOME/conf/jaas-zk.conf,$SPARK_HOME/conf/carbon.properties,$SPARK_HOME/conf/jets3t.properties,$SPARK_HOME/conf/topology.properties,$SPARK_HOME/conf/mapred-site.xml \
--files $localroot/config/logback.xml,\
$localroot/config/hbase-site.xml,$localroot/config/kdc.conf,${uploadFiles} \
--class com.huawei.rcm.newsfeed.boxrcm.nearby.CityInfoParse \
--jars $localroot/lib/bcprov-ext-jdk15on-1.68.jar,\
$localroot/lib/CryptoUtil-1.1.5.304.jar,\
$localroot/lib/commons-pool2-2.8.1.jar,\
$localroot/lib/jedis-2.9.0.jar,$localroot/lib/com.huawei.dcs.dcsdk.core-1.6.18.101.jar,$localroot/lib/com.huawei.dcs.dcsdk.support.onejar-1.6.18.101.jar,$localroot/lib/gpaas-middleware-common-2.2.5.101.jar,\
$app_jarpath \
$arg1 \
$arg2 \
$arg3 \
但很难查到pyspark任务的资源指定配置。
其实很相似，方法如下：
keytab_path=/home/testuser/wdbkeytab/user.keytab
anaconda_archive=hdfs://teset/anaconda3.tar.gz#anaconda_pack
application_name=task_id_$1_$2
pyspark_python="./anaconda_pack/anaconda3/bin/python"
spark-submit --master yarn --deploy-mode cluster --name $application_name \
--driver-cores 2 \
--driver-memory 64G \
--queue $queue \
--num-executors 50 \
--executor-memory 3g \
--executor-cores 2 \
--principal $principal \
--keytab $keytab_path \
--archives $anaconda_archive \
--conf spark.yarn.appMasterEnv.PYSPARK_PYTHON=$pyspark_python \
--conf spark.executorEnv.PYSPARK_PYTHON=$pyspark_python \
--conf spark.driver.maxResultSize=10G \
--conf spark.default.parallelism=1000 \
--conf spark.speculation=true --conf spark.speculation.interval=60000 --conf spark.speculation.quantile=0.85 \
--conf spark.hadoop.mapreduce.input.fileinputformat.input.dir.recursive=true \
--conf spark.security.credentials.hbase.enabled=true \
--conf spark.hadoop.validateOutputSpecs=false \
--conf spark.yarn.user.classpath.first=true \
--conf spark.executor.memoryOverhead=40960 \
--conf spark.yarn.am.waitTime=1000s \
--py-files test.py \
