1:安装好hive,准备启动的时候出现下面的错误(由于hive是基于Hadoop的,所以必须先将你的集群启动起来,我就是没有启动集群,直接启动hive导致的错误): [root@master bin]# ./hive Logging initialized -bin/lib/hive-common-.jar!/hive-log4j.properties Exception failed on connection exception: java.net.ConnectException: Con…

1:练习spark的时候,操作大概如我读取hdfs上面的文件,然后spark懒加载以后,我读取详细信息出现如下所示的错误,错误虽然不大,我感觉有必要记录一下,因为错误的起因是对命令的不熟悉造成的,错误如下所示: scala> text.collect java.net.ConnectException: Call From slaver1/ failed on connection exception: java.net.ConnectException: Connection refused;…

先看解决方案,再看唠嗑,唠嗑可以忽略. 解决方案: 使用start yarn.sh启动yarn就可以了. 唠嗑: 今天学习Spark基于Yarn部署.然后总以为Yarn是让Spark启动的,提交程序的时候Yarn就会启动~!于是乎我就只开启了Spark程序,没开启Yarn,然后执行提交 ./spark-submit --class org.apache.spark.examples.JavaSparkPi \ --master yarn \ --deploy-mode cluster \ --d…
