Subject Re: Not able to execute MRv2
Date Tue, 09 Aug 2011 17:45:43 GMT
Hi Praveen,
 This is an issue because of incompatible versions of avro. This occurs if you have avro 1.3.2
in your cp. We use avro 1.4.

For the time being you can remove any occurence of avro 1.3.2. jar in your classpath and that
should get you out of the error below.

For fixing it  in the right manner there is a jira open:

https://issues.apache.org/jira/browse/HADOOP-7264

Fixing that should get rid of this error.

Hope that helps.

thanks
mahadev
