Subject Re: Connection Refused error on Hadoop2.6 running Ubuntu 15.04 Desktop on Pseudo-distributed mode
Date Mon, 27 Apr 2015 10:50:04 GMT
Wellington:
I have done it at installation time. I shall try once again. However, request you look at
this URL, and maybe let me know your views/suggestions. BTW, if I uninstall and re-install
this error goes away for that session.

Thanks.

 Hello Anand,
This error means  NN could not find it's metadata directory. You probably need to run "hadoop
namenode -format" command before trying to start hdfs.
…2015-04-27 15:21:42,696 WARN org.apache.hadoop.hdfs.server.namenode.FSNamesystem: Encountered
exception loading fsimageorg.apache.hadoop.hdfs.server.common.InconsistentFSStateException:
Directory /tmp/hadoop-anand_vihar/dfs/name is in an inconsistent state: storage directory
does not exist or is not accessible.…
Running the mentioned command will create this directory. You may also want to define a different
location for NN metadata directory, by setting "dfs.namenode.name.dir" property in hdfs-site.xml.

 There might be some FATAL/ERROR/WARN or Exception messages in this log file that can explain
why NN process is dying. Can you paste some of the last lines on the log file?
