hadoop file missing when bin/haoop jobtracker is run on cygwin

Question

I am following this tutorial http://ebiquity.umbc.edu/Tutorials/Hadoop/14%20-%20start%20up%20the%20cluster.html They are using hadoop version hadoop-0.19.1. The version that I installed is hadoop-0.20.204.0. I can format the HDFS fine using this command bin/hadoop namenode -format.

The problem arises when i want to use the jobtracker which says no such file or directory when i use this command bin/haoop jobtracker. Also when i try and run data node and tasktracker the same error message is returned. Have the files been moved to a different place or have I not installed it correctly.

the file is missing from the download package. The error message is when I am in the folder hadoop-0.20.204.0 on the cygwin system.

here is the hdfs being formatted

$ bin/hadoop namenode -format

path to environmental variable C:\Program Files (x86)\Java\jdk1.6.0_32

I ran the command again

ALEXDEV@ALEXDEV-PC ~/hadoop-0.20.204.0 $ bin/hadoop namenode Error: JAVA_HOME is not set.

I am not sure how todo the escape character for the brackets in the path (x86) part

Answer 1

Sounds like unescaped spaces in the path name that it infers. Try moving the hadoop directory to the root of your drive (so something like c:\hadoop\" or similar.
