Is it possible to build with h2 and h3 into one target? I assume that there's only one jar there, relevant for hadoop 3 or hadoop 2. If there's two jar there, then pig won't start: Error: Could not find or load main class org.apache.pig.Main Should we prepare for this case too? Not sure what is the best approach here. - Nandor ----------------------------------------------------------- This is an automatically generated e-mail.
