[jira] [Created] (HADOOP-8408) MR doesn't work with a non-default
ViewFS mount table and security enabled
Aaron T. Myers created HADOOP-8408:
--------------------------------------
Summary: MR doesn't work with a non-default ViewFS mount table and security enabled
Key: HADOOP-8408
URL: https://issues.apache.org/jira/browse/HADOOP-8408
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 2.0.0
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
With security enabled, if one sets up a ViewFS mount table using the default mount table name, everything works as expected. However, if you try to create a ViewFS mount table with a non-default name, you'll end up getting an error like the following (in this case "vfs-cluster" was the name of the mount table) when running an MR job:
{noformat}
java.lang.IllegalArgumentException: java.net.UnknownHostException: vfs-cluster
{noformat}
