Arpit Gupta commented on FALCON-223:
------------------------------------
If we moved falcon in the CP first could it not then cause issues when hadoop
client code tries to use something from commons-lang?
I think one way we can do this is create a new env var along the lines of
FALCON_CLASSPATH_FIRST which defaults to false/no. If its set to yes then we
add it first before hadoop.
That way you can keep the existing behavior and only change it in specific
cases.
> hive-exec bundles protobuf-2.4.1 which is incompatible with hadoop-2
> requiring protobuf-2.5

> This is not an issue with hadoop-1 but only hadoop-2.
> This is fixed in hive-0.13 (HIVE-5112) but its not released yet for us to
> upgrade. A quick fix is to change the falcon startup scripts to set the
> hadoop classpath prior to falcon dependencies.
