Even when I add /usr/bin/env it doesn't work.

To use Hadoop command you need to use kinit command to get a Kerberos ticket first, this kinit is generated automatically for me ( in the command line) but krontab ignores this .
My question is how to inform krontab so it considers this ticket ??

mv

MV(1)									FSF								     MV(1)

NAME

       mv - move (rename) files

SYNOPSIS

       mv [OPTION]... SOURCE DEST
       mv [OPTION]... SOURCE... DIRECTORY
       mv [OPTION]... --target-directory=DIRECTORY SOURCE...

DESCRIPTION

       Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY.

       Mandatory arguments to long options are mandatory for short options too.

       --backup[=CONTROL]
	      make a backup of each existing destination file

       -b     like --backup but does not accept an argument

       -f, --force
	      do not prompt before overwriting equivalent to --reply=yes

       -i, --interactive
	      prompt before overwrite equivalent to --reply=query

       --reply={yes,no,query}
	      specify how to handle the prompt about an existing destination file

       --strip-trailing-slashes remove any trailing slashes from each SOURCE
	      argument

       -S, --suffix=SUFFIX
	      override the usual backup suffix

       --target-directory=DIRECTORY
	      move all SOURCE arguments into DIRECTORY

       -u, --update
	      move only when the SOURCE file is newer than the destination file or when the destination file is missing

       -v, --verbose
	      explain what is being done

       --help display this help and exit

       --version
	      output version information and exit

       The  backup  suffix  is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.  The version control method may be selected via the --backup
       option or through the VERSION_CONTROL environment variable.  Here are the values:

       none, off
	      never make backups (even if --backup is given)

       numbered, t
	      make numbered backups

       existing, nil
	      numbered if numbered backups exist, simple otherwise

       simple, never
	      always make simple backups
