Hi, I don't know what mistake I did that now I get this error
INFO ipc.Client:Retrying connect toserver:localhost/127.0.0.1:54310.Already tried2time(s);retry policy isRetryUpToMaximumCountWithFixedSleep(maxRetries=10,sleepTime=1SECONDS) INFO ipc.Client:Retrying connect toserver:localhost/127.0.0.1:54310.Already tried3time(s);retry policy isRetryUpToMaximumCountWithFixedSleep(maxRetries=10,sleepTime=1SECONDS) I saw the wiki page for that message and all other resources state that the namenode has not been started yet. However I tried "stop-all.sh && start-all.sh" multiple times. In fact I see java processes regarding Hadoop. More info: core-site.xml <property> <name>fs.default.name</name> <value>hdfs://localhost:54310</value> </property> mapred-site.xml <property> <name>mapred.job.tracker</name> <value>localhost:54311</value> </property> Any more idea on that?
