Class NonConfiguredVolume

java.lang.Object
  org.apache.accumulo.core.volume.NonConfiguredVolume

All Implemented Interfaces:

Volume

public class NonConfiguredVolume
extends Object
implements Volume

Volume implementation which represents a Volume for which we have a FileSystem but no base path because it is not configured via Property.INSTANCE_VOLUMES This is useful to handle volumes that have been removed from accumulo-site.xml but references to these volumes have not been updated. This Volume should never be used to create new files, only to read existing files.

Constructor Summary

NonConfiguredVolume(org.apache.hadoop.fs.FileSystem fs)

Method Summary

boolean	equals(Object o)
String	getBasePath() The base path which Accumulo will use within the given FileSystem

boolean	isValidPath(org.apache.hadoop.fs.Path p) Determine if the Path is valid on this Volume.
org.apache.hadoop.fs.Path	prefixChild(org.apache.hadoop.fs.Path p) Convert the given Path into a Path that is relative to the base path for this Volume
org.apache.hadoop.fs.Path	prefixChild(String p) Convert the given child path into a Path that is relative to the base path for this Volume
