问题分析：

问题一

org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.StandbyException): Operation category WRITE is not supported in state standby

此报错因为程序部署在141机器，141机器为namenode备节点

问题二

fs = FileSystem.get(URI.create("hdfs://10.43.159.142:9000"),conf); 没有加用户标识

Call From dap141-159/10.43.159.141 to dap142-159:9000 failed on connection exception: java.net.ConnectException: 拒绝连接; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

此报错因为程序部署在141机器，代码去连dap142-159:9000 拒绝连接

java创建hdfs目录和文件，fs = FileSystem.get(URI.create("hdfs://10.43.159.142:9000"),conf); URI要配置nameNode节点信息

问题三

jdk版本不对

本地代码编译是基于java1.7编译的

主要原因是因为mask-web工程启动的jdk是1.7，需要修改为1.8

命令行参数：spark.executorEnv.JAVA_HOME=/usr/java8/jdk

spark.yarn.appMasterEnv.JAVA_HOME=/usr/java8/jdk

spark.yarn.queue=mr

spark.master=spark://xinhuo113:7077,xinhuo111:7077 standalone模式下需要

问题四

六月 12, 2018 1:47:53 下午 org.apache.spark.launcher.OutputRedirector redirect

INFO: Error: Cluster deploy mode is not compatible with master "local"

六月 12, 2018 1:47:53 下午 org.apache.spark.launcher.OutputRedirector redirect

INFO: Run with --help for usage help or --verbose for debug output

不设置如下参数，运行时是local模式 提交报错

先设置yarn模式运行

.setMaster("yarn")

.setDeployMode("cluster")

报错用户权限，需要赋权 先默认以mr用户启动工程

六月 12, 2018 2:01:42 下午 org.apache.spark.launcher.OutputRedirector redirect

INFO: Exception in thread "main" org.apache.hadoop.yarn.exceptions.YarnException: Failed to submit application_1528709704391_0001 to YARN : User root cannot submit applications to queue root.root

client模式和cluster模式的区别

jar包和配置文件都在hdfs目录： 注：集群模式cluster 存在读不到/etc/spark/conf/hive-site.xml文件的情况，需要手动指定

spark-submit --master yarn --deploy-mode cluster --executor-cores 2 --executor-memory 4g --conf spark.sql.shuffle.partitions=800 --class anonymous.main.KLMainSpark hdfs://nameservice/job/KLTAnonymous-1.0-SNAPSHOT.jar hdfs://nameservice/job/KAn_DoubleNum.xml

此命令会读不到hive-site文件，

2018-06-13 09:43:43,421 WARN org.apache.hadoop.hive.metastore.ObjectStore: Failed to get database default, returning NoSuchObjectException

指定hive-site.xml文件

yarn-cluster模式运行报错：为分布式运行，需要在hdfs目录下找文件KAn_DoubleNum.xml 分发到每台机器
