Issue in Datanode (using CDH4.1.2)
Hi All,
I am facing on strange issue, That is In a cluster having 1k machine i
could able to start and stop
NN,DN,JT,TT,SSN. But the problem is under Name node Web-URL
it is showing only one datanode . I tried to connect node through ssh also
it was working file and i have assigned NNURL: port in core-site
http://namenode:50070
Again I have checked with datanode logs, and I got the message like this:
2013-02-28 06:59:01,652 WARN
org.apache.hadoop.hdfs.server.datanode.DataNode: Problem connecting to
server: hadoophost1/192.168.1.1:54310
2013-02-28 06:59:07,660 INFO org.apache.hadoop.ipc.Client: Retrying connect
to server: hadoophost1/192.168.1.1:54310. Already tried 0 time(s); retry
policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1
SECONDS)
Regards,
samir.
