I tried to run a simple program in hadoop using Windows-Cygwin. I am able to start the namenode . The jobtracker start however fails with exception : FATAL mapred.

Hdfs-site. Xml configurations : fs.default. Name hdfs://localhost:9100 mapred.job.

Tracker localhost:9101 dfs. Replication 1 Thanks! Hadoop link|improve this question edited yesterdaySenthil Prabhu14610 asked yesterdayVani Jayram11.

The problem is the following lines should on into mapred-site. Xml and NOT hdfs-site. Xml, mapred.job.

Tracker localhost:9101 By the way why are you trying to run Hadoop in Windows? For development? You don't have a linux machine or reluctant to install one?

One more thing, you usually put this property in core-site. Xml not hdfs-site. Xml, fs.default.

Name hdfs://localhost:9100.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
