Using this link ,tried installing Hadoop version - 2.2.0(single node cluster)in ubuntu 12.04(64 bit machine)

http://bigdatahandler.com/hadoop-hdfs/installing-single-node-hadoop-2-2-0-on-ubuntu/

while formatting the hdfs file system via namenode using the following command

hadoop namenode -format

when i'm doing that ,getting the following issue,

14/08/07 10:38:39 FATAL namenode.NameNode: Exception in namenode join java.lang.RuntimeException: org.xml.sax.SAXParseException; systemId: file:/usr/local/hadoop/etc/hadoop/mapred-site.xml; lineNumber: 27; columnNumber: 1; Content is not allowed in trailing section.

What shall i need to do inorder to solve the following issue?

Mapred-site.xml:

  • Is there anything more in the mapred-site.xml? I cant see any line number 27. – Abhishek Aug 07 '14 at 06:08
  • now copied the whole thing check it out – user3532122 Aug 07 '14 at 06:16
  • Still cannot see line 27. If You left an [enter] press after last line,maybe its causing issue. – Abhishek Aug 07 '14 at 07:00
  • Try implementing from [this](http://raseshmori.wordpress.com/2012/09/23/install-hadoop-2-0-1-yarn-nextgen/) – Y.Prithvi Aug 07 '14 at 10:54
  • Like @Abhishek said, everything so far hints at a problem on line 27 of the XML, but unfortunately we're not seeing a line 27 come through in your post. You might try looking at a hex representation of the file (run something like `hexdump` or `xxd` on the file). That could tell you if there is something odd at the end of the XML, like a control character. – Chris Nauroth Aug 07 '14 at 15:03
  • ya that was an issue....Fixed it .........Thanks for the help – user3532122 Aug 16 '14 at 05:31

Probably some caracter in your XML that you forget to erase. Please post your full XML. Like @Abhishek said!
