Hi YONG YONG CHENG, First of all thanks for reply. I used the path told by you as JAVA_HOME but still its showing same problem. After this I wrote command in cygwin as export JAVA_HOME=C:\\cygwin\\home\\HadoopAdmin\\java
then it started running. Same happened with other export commands in the file C:\cygwin\home\HadoopAdmin\hadoop-0.18.3\conf\hadoop-env.sh That means cygwin is unable to read commands from hadoop-env.sh file. Can you suggest some thing on this.
