Hadoop TaskTracker and JobTracker don t start with start-dfs sh

Question

I am trying to set up hadoop 0.22.0 on my laptop for learning purpose.

When i run start-dfs.sh and then do jps, i get the following output.

18106 Jps
17269 NameNode
17556 DataNode
17845 SecondaryNameNode

But I can't see the TaskTracker or JobTracker running. So, can anyone please tell me what could I be missing. I am a total newbie and don't know what information is required. So, please let me know.

Answer 1

You must run the start-dfs..sh too.

So when you run start-all.sh, you must have gotten this message

echo "This script is Deprecated. Instead use start-dfs.sh and start-mapred.sh"
