Hi,
I am new to Hadoop and I want to learn it from scratch. I have installed
Cloudera Manager Free Edition on a single cluster (OS: CentOS). Which is
working fine apart from Mapreduce which is having bad health for
tasktracker.
I need help in two areas.
1. Please provide me TaskTracker Local Data Directory List mapred.local.dir
and JobTracker Local Data Directory
mapred.local.dir to start mapreduce without any issue.
2. How to write first program of mapreduce and where I can write this and
execute the same through the CM. If I am doing the same in command prompt
then what kind of benefit I am getingt through the services I have hosted
through CM.
If possible please suggest few links of beginners. to go through.
I am waiting for a quick response on my queries.
