Hi everyone, My slave machine (cloud15) the datanode shows this log. It doesn't connect to the master (cloud6).
2013-08-07 13:44:03,110 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: cloud15/192.168.188.15:54310. Already tried 9 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS) 2013-08-07 13:44:03,110 INFO org.apache.hadoop.ipc.RPC: Server at cloud15/ 192.168.188.15:54310 not available yet, Zzzzz... But when I type jps command on slave machine DataNode is running. This is my file core-site.xml in slave machine (cloud15): <configuration> <property> <name>hadoop.tmp.dir</name> <value>/app/hadoop/tmp</value> <description>A base for other temporary directories.</description> </property> <property> <name>fs.default.name</name> <value>hdfs://cloud15:54310</value> <description>The name of the default file system. A URI whose scheme and authority determine the FileSystem implementation. The uri's scheme determines the config property (fs.SCHEME.impl) naming the FileSystem implementation class. The uri's authority is used to determine the host, port, etc. for a filesystem.</description> </property> </configuration> In the master machine I just swap cloud15 to cloud6. In the file /etc/host I have (192.168.188.15 cloud15) and (192.168.188.6 cloud6) lines, and both machines access through ssh with out password. Am I missing anything? Thanks in advance!
