Subject: Error running unit tests from eclipse (weird classpath issue)

[Pavel Chadnov <pa...@gmail.com>]

Hey Guys,


I'm trying to run Hive unit tests on eclipse and have few failures. One of
the interesting one is throwing this exception as shown below when ran from
eclipse, this one passes fine from the console.

I tried adding hadoop-shims project in the classpath by manually adding
them but no luck. Would really appreciate any help here.


Thanks,
