Keith Turner created ACCUMULO-2044:
--------------------------------------
Summary: Accumulo fails when instance.volumes and fs.default.name
are disjoint
Key: ACCUMULO-2044
URL: https://issues.apache.org/jira/browse/ACCUMULO-2044
Project: Accumulo
Issue Type: Sub-task
Reporter: Keith Turner
Fix For: 1.6.0
In the hadoop core-site.xml I had the following.
{noformat}
<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>
{noformat}
In accumulo-site.xml, I had the following.
{noformat}
<property>
<name>instance.volumes</name>
<value>hdfs://ip-10-1-3-10:9000,hdfs://ip-10-1-3-11</value>
</property>
{noformat}
When I tried to initialize accumulo I saw the following error. I think the
problem is ZooUtil.getInstanceIDFromHdfs() just gets the default filesystem.

In testing I have done in the past with multiple namenode, the default namenode
configured for hadoop was the same as the first namenode I configured for
Accumulo. In this case the configs are disjoint, I may see other errors using
this configuration.
