Question

我已经获得了Cloudera VM用于学习Hadoop。我在java中创建了一个基本的wordcount程序并将其导出到jar文件中。我试过运行jar文件，但我得到了这个：

INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8032
ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 1 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 2 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)

...

它会一直持续到10次。我以前从未与Hadoop合作过，所以我很新，不知道我在做什么。任何帮助表示赞赏。

其他一些信息：

whereis hadoop

hadoop: /usr/bin/hadoop /etc/hadoop /usr/lib/hadoop /usr/share/man/man1/hadoop.1.gz

核心-site.xml中：

<property>
    <name>fs.defaultFS</name>
    <value>hdfs://quickstart.cloudera:8020</value>
</property>

HDFS-site.xml中：

 <property>
    <name>dfs.replication</name>
    <value>1</value>
 </property>

无法在Cloudera VM上运行Hadoop Jar
