namenode -upgrade problem

bharath vissapragada 2009-08-03, 19:08

Hi all ,

I have noticed some problem in my cluster when i changed the hadoop version
on the same DFS directory .. The namenode log on the master says the
following ..
ile system image contains an old layout version -16.
An upgrade to version -18 is required.
Please restart NameNode with -upgrade option.

See bolded text above -- you need to run namenode -upgrade to upgrade your
metadata format to the current version.

Todd thanks for replying ..

I stopped the cluster and issued the command

"bin/hadoop namenode -upgrade" and iam getting this exception

Are you sure you stopped all the daemons? Use 'sudo jps' to make sure :)

Re: namenode -upgrade problem

bharath vissapragada 2009-08-05, 17:53

yes .. I have stopped all the daemons ... when i use jps ...i get only ...
"<pid> Jps"

Actually .. i upgraded the version from 18.2 to 19.x on the same path of
hdfs .. is it a problem?

Re: namenode -upgrade problem

Aaron Kimball 2009-08-05, 19:21

The only time you would need to upgrade is if you've increased the Hadoop
version but are retaining the same HDFS :) So, that's the normal case.

What does "netstat --listening --numeric --program" report?
