Keith Turner resolved ACCUMULO-2045.
------------------------------------
Resolution: Not A Problem
I changed the following in accumulo-site.xml
{noformat}
<value>viewfs://nn1,viewfs://nn2</value>
{noformat}
to the following and then init ran ok.
{noformat}
<value>viewfs:///nn1,viewfs:///nn2</value>
{noformat}
> Accumulo fails to init when using viewfs://

> 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.
> {noformat}
