--------------------------------------
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.
