Subject AccessControlException when calling copyFromLocalFile()
Date Wed, 02 Jun 2010 18:56:40 GMT
When the user calling FileSystem.copyFromLocalFile() doesn't have permission
to write to certain hdfs path:
Thread [main] (Suspended (exception AccessControlException))

    DistributedFileSystem.mkdirs(Path, FsPermission) line: 262
    DistributedFileSystem(FileSystem).mkdirs(Path) line: 1162
    FileUtil.copy(FileSystem, Path, FileSystem, Path, boolean, boolean,

    GridM2mInstallation.copyInputFiles(FlowConfigurations$FlowConf) line:

Passwordless ssh has been setup for current user, tyu, on localhost and user
hadoop on Namenode.
I want to get opinion on how I can programmatically get pass the above
exception - by specifying user as hadoop, maybe ?
