Re: ERROR 2999: Unexpected internal error. Failed to create DataStorage
Kiran,

I guess your problem is config file. You have different value of
fs.default.name in hdfs-site.xml (10.0.0.61:8020) then in mapred-site.xml
and core-site.xml (10.0.0.61:9000) Make them consistent and then try.

Hope it helps,
Ashutosh
