Hi, Am quite new to using this hadoop. I set the single node and tried running the sample map-reduce programs in that. They worked fine. 1)I want to run the distributed cache code(single node or 2-node cluster) and view the output. But i dont understand how to specify the input files, setting up the path in JobConf.java and where to add the functions specified in the instruction. 2)I also want to view the output files(logs). 3)They are talking about speculative execution and it is set to true by default in JobConf. But where exactly the actual logic of speculative execution could be found in the hadoop installation? I mean the specific code which gets executed when it is called.
Waiting for guidance.. regards KulliKarot
