hi when I do some hive basic query like "select * from table" using Mapred execution engine, my job is failing with these kind of errors:
Yarn Logs: Error: could not find or load main class 800
RM logs: ==

@Mondi I have not seen this specific 800 error. You should be able to find deeper information in the actual application logs. They are hard to find, several clicks deep in the Yarn UI. Depending on your application, there can be many log files, and you will need to inspect each one for deeper details in the failure.
