When I tried to run hadoop in my Linux box, I got a strange error:<\/p>\n

bin\/hadoop: line 53: \/home\/hzhang\/tools\/hadoop-0.20.203\/bin
\n\/home\/hzhang\/tools\/hadoop-0.20.203\/bin\/hadoop-config.sh: No such file or directory<\/code><\/p>\n

It said the hadoop-config.sh is missing, but clearly it’s there in my machine. After hair-scratching for quite a bit, I found out that it’s the line before 53 that caused error<\/p>\n

bin=`dirname \"$0\"`
\nbin=`cd \"$bin\"; pwd`
\n<\/code>
\nThe reason is that I activated CDPATH in my shell, and the $bin variable therefore contains the same path repeated twice. All I have to do is turn it off by the following command:
\n$ unset CDPATH<\/code><\/p>\n","protected":false},"excerpt":{"rendered":"
