Luca Telloli updated HADOOP-5188:
---------------------------------
Attachment: HADOOP-5188.patch
the attached patch supports:
- parsing dfs.name.edits.dir arguments as URI
- introducing a new abstraction named LoggingDevice. The subclass named
FileLoggingDevice should incorporate StorageDirectory (work in progress). The
idea is that FileLoggingDevice should be treated as the current
StorageDirectory (when the directory is of type EDITS or IMAGE_AND_EDITS) while
other types of logging should be treated according to their respective
properties.
Two methods (namely getInputDeviceClassName and getOutputDeviceClassName)
should get the class name of the EditLogInput/OutputStreams associated with
this type of device.
the patch passes successfully namenode unit tests
> Modifications to enable multiple types of logging
