Hi,
I have the standard Hadoop vmware image installed (I think it contains
hadoop 0.18). I checked out and run hive based on the instructions on your
wiki.
I created a simple table containing 7 columns and loaded data into it.
Now, when I do "select a.* from mytable a;" everything works fine.
But, when trying "select a.mycolumn from mytable a;" I get the following
exception:
java.lang.AbstractMethodError:

Should hive work with hadoop 0.18, or do I need to upgrade? Or do I need to
update/rebuild hive?
Thanks,
Martin
