Subject Re: Can we use method CopyToLocalFile() to copy HDFS files to windowsXP?
Date Fri, 03 Dec 2010 01:03:21 GMT
Hi Jeff,

Yeah, you're quite right. I've tried it and it works well with $CYGWIN_HOME/bin on windows'
PATH.

But I'm still a bit confused on the reason. Why should chmod be invoked from $CYGWIN_HOME/bin
and which mode was changed by it?


Much appreciated,
siqin^^;;

You need to install cygwin, and put $CYGWIN_HOME/bin on your path
