             Summary: Accumulo fails to init when using viewfs://
                 Key: ACCUMULO-2045
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2045
             Project: Accumulo
          Issue Type: Bug
            Reporter: Keith Turner
            Assignee: Keith Turner
             Fix For: 1.6.0


I was trying to use viewfs:// with hadoop 2.2.0 and two namenodes.   I tried to run {{accumulo
init}} and it failed.

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

{noformat}
<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>
{noformat}

I had the following in my accumulo-site.xml

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

I saw the following exception.  At this point I am not sure if this is a config problem, accumulo
bug, or hadoop bug.
