Does "netstat -an | grep LISTEN" show these ports being listened on?
Can you stat hdfs from the command line e.g.: hdfs dfsadmin -report hdfs fsck / hdfs dfs -ls / Also, check out /var/log/hadoop or /var/log/hdfs for more details. john From: Mahmood Naderan [mailto:[email protected]] Sent: Thursday, March 27, 2014 5:04 AM To: [email protected] Subject: ipc.Client: Retrying connect to server Hi, I don't know what mistake I did that now I get this error INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:54310. Already tried 2 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS) INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:54310. Already tried 3 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS) 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?
