Guido Serra aka Zeph commented on HIVE-2055:
--------------------------------------------
I have the same issue... I setted up an environment with Cloudera Manager, the
latest with CDH4
the libraries are available under /usr/lib/hive/lib , and they are correctly in
the CLASSPATH that gets computed by the hive-env.sh script (I did a print out
of that), but in any case... they do not seem to get picked up, instead if I
force them from command line, they work
