    [ https://issues.apache.org/jira/browse/TAJO-885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14040330#comment-14040330 ] 

Jihoon Son commented on TAJO-885:
---------------------------------

Hi [~prafulla], 
I met the same error before, and it was due to the wrong compile option of hadoop version.
For example, if you use hadoop 2.2.0, tajo should be built with the option '-Dhadoop.version=2.2.0'.
Would you check that tajo is built for the proper hadoop version?
