I have a couple of questions regarding job result and schema. The context is that I'm trying to create a custom entry point for Pig that takes a script, executes it, and always stores the last declared alias/variable in a file. Would appreciate any insights to the 2 questions I have below or any advice in general.
1. I'm looking to automatically dump or store the last variable/alias that the user has set. I know PigServer.getAliasKeySet or getAliases will return a Set or Map of the alias. But they are unordered, is there a way to get an ordered list of aliases? 2. I'm interested in getting the result schema and the raw result set. Is the best way to do this just PigServer.dumpSchema(alias) to get the result schema, and PigServer.openIterator(alias) to get the resulting Tuples? Thanks, Jeff
