通过Cloudera Manager 4.5安装Hadoop之后，HDFS仅指向本地文件系统

Question

After install Cloudera Manager 4.5 I find that it's not configured to point to the correct default filesystem. If I run haddop fs -ls / from one of the tasktracker/datanode boxes I just get the local filesystem.

But when I check core-site.xml from in cloudera, I see this setting, which seems like it might be correct:

<property>
  <name>fs.defaultFS</name>
  <value>hdfs://hadoop-namenode1:8020</value>
</property>

Any idea what I should be looking for here exactly?

Answer 1

Ah, it wasn't clear to me that you need to "deploy client configuration" from cloudera manager.

Running this command helped me figure that out:

davidparks21@hadoop-reducedslot2:~$ hdfs getconf -confKey fs.defaultFS
