Spark启动报错问题

今天准备把Spark和Hive进行集成一下，当启动Spark的时候，报了如下错误：

[rzf@hadoop100 spark]$ bin/spark-shell 
21/06/04 11:52:20 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

spark连接HDFS拒绝连接，其实是犯了一个很低级的错误：

检查配置信息发现，在hdfs配置文件中，namenode指定的地址如下，并且使用的端口是9000，

<property>
    <!-- 指定HDFS中NameNode的地址 -->
    <name>fs.defaultFS</name>
        <value>hdfs://hadoop100:9000</value>
</property>

但是在spark的spark-defaults.conf配置文件中spark.eventLog.dir配置项，端口号使用的是8020，所以报错.
