Description

I was trying to use viewfs:// with hadoop 2.2.0 and two namenodes. I saw multiple failures when trying to do this. I will open subtickets for specific failures.

I had the following in my hadoop core-site.xml

<configuration>
  <property>
    <name>fs.default.name</name>
    <value>viewfs:///</value>
  </property>
  <property>
    <name>fs.viewfs.mounttable.default.link./nn1</name>
    <value>hdfs://ip-10-1-3-10:9000</value>
  </property>
  <property>
    <name>fs.viewfs.mounttable.default.link./nn2</name>
    <value>hdfs://ip-10-1-3-11:9000</value>
  </property>
</configuration>

I had the following in my accumulo-site.xml

  <property>
    <name>instance.volumes</name>
    <value>viewfs:///nn1,viewfs:///nn2</value>
  </property>
