However when I try to run a reporting search, that starts a MapReduce job the search fails with an error message like this:</P> <P>JobStartException - Failed to start MapReduce job. Please consult search.log for more information. Message: [Failed to start MapReduce job, name=....] and [Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.]</P> <P>Any ideas what could be happening?</P> Wed, 18 Sep 2013 13:18:08 GMT https://community.splunk.com/t5/Deployment-Architecture/Error-while-running-Hunk-search-Cannot-initialize-cluster/m-p/66408#M22409 Ledion_Bitincka 2013-09-18T13:18:08Z https://community.splunk.com/t5/Deployment-Architecture/Error-while-running-Hunk-search-Cannot-initialize-cluster/m-p/66409#M22410 <P>We've seen this error come up a number of times and the error message (thrown by the Hadoop libraries) is misleading.
