alluxio.hadoop

Class AlluxioFileSystem

java.lang.Object

org.apache.hadoop.fs.AbstractFileSystem

org.apache.hadoop.fs.DelegateToFileSystem

alluxio.hadoop.AlluxioFileSystem

public class AlluxioFileSystem
extends org.apache.hadoop.fs.DelegateToFileSystem

The Alluxio implementation of Hadoop AbstractFileSystem. The implementation delegates to the existing Alluxio FileSystem and is only necessary for use with Hadoop 2.x. Configuration example in Hadoop core-site.xml file:

 <property>
    <name>fs.AbstractFileSystem.alluxio.impl</name>
    <value>alluxio.hadoop.AlluxioFileSystem</value>
 </property>
 

For a long term solution, we need to rewrite AlluxioFileSystem by extending Hadoop's AbstractFileSystem directly.
