Subject HADOOP UPGRADE ISSUE
Date Thu, 22 Nov 2012 06:53:41 GMT

Hi All,

I am trying upgrading apache hadoop-0.20.2 to hadoop-1.0.4.
I have give same dfs.name.dir, etc as same in hadoop-1.0.4' conf files as were in hadoop-0.20.2.
Now I am starting dfs n mapred using

start-all.sh -upgrade

but namenode and datanode fail to run.

1) Namenode's logs shows::

ERROR org.apache.hadoop.hdfs.server.namenode.FSNamesystem: FSNamesystem initialization failed.
java.io.IOException: 
File system image contains an old layout version -18.
An upgrade to version -32 is required.
Please restart NameNode with -upgrade option.

****(  how these file permission showing warnings)*****

in dfs.data.dir are invalid.

Please suggest
