Hi Mohit,
1) Hadoop is more portable with Linux,Ubantu or any non dos file
system.
but you are running hadoop on window it colud be the problem bcz hadoop
will generate some partial out put file for temporary use.
2) Another thing is that your are running hadoop version as 0.19 , I think
if you upgrade the version it will solve your problem. why bcz example what
exactly you are using it is having some problem with FileRead and Write
with Window OS.
3) Check your input file data bcz i could see your mapper is also 0%
4) If your are all right with whole scenario . please could your share your
logs under hadoop<version>/logs
there it self we can trace it very clearly.
Thanks
