Re: under cygwin JUST tasktracker run by cyg_server user, Permission denied .....
Dear Uma,
as you know when we use start-all.sh command, all the outputs saved in
log files,
when i check the tasktracker log file, i see the below error message and
its shutdown.
im really confused, its more than 4 days im working in this issue and
tried different ways but no result.^^

BS.
