Subject Getting error during namenode -format
Date Wed, 11 Jan 2012 20:24:18 GMT


I am in the process of installing hadoop on non-clustered single node
windows xp. SSH installed and running.

Java version: java version "1.5.0_15" it is installed in c:\Program


export JAVA_HOME=/cygdrive/c/Program\ Files/Java/jdk1.5.0_15

When I am executing the command

bin/hadoop namenode -format

I am getting the following error, how to escape "Program Files"?

$ bin/hadoop namenode -format
cygpath: can't convert empty path
/usr/local/hadoop-0.22.0/bin/hadoop-config.sh: line 194:
/cygdrive/c/Program: No such file or directory
cygpath: can't convert empty path
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
