Hello, I configured 0.23 thanks to cloudavenue's <http://www.thecloudavenue.com/2012/01/getting-started-with-nextgen-mapreduce.html>post. My UI seems ok, but reports only one node out of the ten.
My master is running: 18130 DataNode 18264 ResourceManager 18507 NodeManager 19881 NameNode And my slaves are running: DataNode *Since start-all.sh is deprecated, I had to launch it manually, using a for loop!* *Q1: Do I have to write my own script to start the entire cluster??!* Q2: I think I am missing a tasktracker (or its equivalent in 0.23)? Is that the reason why the other nodes dont figure in the UI? Q3: I tried, to submit a simple PI calculation job, and got: > ./bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-0.23.1.jar pi 10 10000 12/05/12 19:21:40 INFO mapreduce.Job: map 0% reduce 0% *12/05/12 19:21:40 INFO mapreduce.Job: Job job_1336859612524_0005 failed with state FAILED due to: Application application_1336859612524_0005 failed 1 times due to AM Container for appattempt_1336859612524_0005_000001 exited with exitCode: 1 due to: * *.Failing this attempt..
