Hi All,

I see there are some hadoop packages present inside hive-exec jar. (for
example org.apache.hadoop.fs etc.). My guess is that these classes extend
some hadoop interfaces/ functionality. However is it required for them to
retain the same package structure? I am asking because I am trying to run
Hive under an OSGi environment and duplicate packages coming from Hadoop
and Hive are causing issues under OSGi.

Yes. This has bitten me before as well. Hive-exec jar builds in some
things from commons lang and commons util. They are needed by
hive-exec jar itself so getting them from distributed cache/auxjars
does not work well. I think the solution is we should probably
repackage commons util into hive-commons so their is not conflicts.

Open up a jira for discussion.

HI Edward,

Thanks for the reply. Please find the created JIRA at [1]. However for
currently for getting this working would moving these classes to a separate
package structure work? I am willing to patch Hive sources to get this
working if it comes to that. How did you get around the problems you faced?

I 'fixed' it by downgrading my common-util to the same version as hive
so the signatures would not conflict.
