I was trying out Hadoop (Sandbox 1.3 Version) for the first time, and was doing the Hello World Tutorial.
Firstly, I got an error while installation because the clusterservices.txt file mentioned d: as log file repositories, and I had only a C: drive on my Server.
I split the C: into E: (D: was the DVD Driver) with the sizes:
C: 7.94GB free of 23.4 GB
E: 15.6GB free of 16.4 GB
Then, I modified the few lines at the top of clusterservices.txt to refer to E: instead of D:
The installation was successful.
When I reach the next step:
One services failed, ‘namelog’.
I looked at the logs but I could not figure out why the failure was happening.
I am attaching the log directory for your help.

org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory E:hdpdatahdfsnn is in an inconsistent state: storage directory does not exist or is not accessible.
THere is only a E:hdpdatahdfsdn directory in that directory.
It will be most helpful if you can tell me what the error was, and where I went wrong.
Awaiting an early reply,
