原因分析

今天我将spark的history-server打开了，测试的时候用的好好的，但是一会发现启动不了spark作业提交不了。
通过分析日志并查看HDFS的Web界面，发现应该是我的spark连接不到HDFS的ActiveNN，而spark启动就需要连接HDFS的服务只有写入job日志这一项，所以我查看了指定sparkJob日志写入路径的spark-defaults.conf文件，果然路径指定的是standByNN

spark.eventLog.dir              hdfs://hadoop002:8020/g6_direcory

所以spark不能通过连接standByNN将日志写入HDFS

解决

将spark-defaults.conf和spark-env.sh 里面日志目录文件路径从单一NN改为命名空间的路径就好
我的命名空间是

        
                fs.defaultFS
                hdfs://ruozeclusterg6
        

修改spark-defaults.conf

spark.eventLog.enabled           true
spark.eventLog.dir              hdfs://ruozeclusterg6:8020/g6_direcory

修改spark-env.sh

SPARK_HISTORY_OPTS="-Dspark.history.fs.logDirectory=hdfs://ruozeclusterg6:8020/g6_direcory"

测试
