org.apache.accumulo.core.volume
Interface Volume

All Known Implementing Classes:

NonConfiguredVolume, VolumeImpl

public interface Volume

Encapsulates a FileSystem and a base Path within that filesystem. This also avoid the necessity to pass around a Configuration.

Method Summary

String	getBasePath() The base path which Accumulo will use within the given FileSystem
org.apache.hadoop.fs.FileSystem	getFileSystem() A FileSystem that Accumulo will use
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

Method Detail

getFileSystem

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

A FileSystem that Accumulo will use

getBasePath

String getBasePath()

The base path which Accumulo will use within the given FileSystem

prefixChild

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

Parameters:

p - The suffix to use

Returns:

A Path for this Volume with the provided suffix

prefixChild

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

Parameters:

p - The suffix to use

Returns:

A Path for this Volume with the provided suffix

isValidPath

boolean isValidPath(org.apache.hadoop.fs.Path p)

Determine if the Path is valid on this Volume. A Path is valid if it is contained in the Volume's FileSystem and is rooted beneath the basePath
