[jira] [Commented] (AVRO-1451) Getting org.apache.hadoop.ipc.RPC$VersionMismatch error when reading avro file from terminal

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-1451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13889692#comment-13889692 ] 

Doug Cutting commented on AVRO-1451:
------------------------------------

The avro-tools jar in 1.7.4 includes libraries from Hadoop 0.20.205, which is not compatible with the Hadoop 0.20.2-cdh3u5 cluster you're attempting to run it against.  You could rebuild the avro-tools jar, or it might be simpler to combine the appropriate jar files on the command line with something like:

  java -cp 'avro-tools-1.7.4-nodeps.jar:hadoop-0.20.2-cdh3u5.jar:...' org.apache.avro.tool.Main

(Where I put the "..." you'll need to add other required jars.)
