I have no idea how and where to set all those parameters. 2. Another question is about Hive, I was using beeline to test if Hive is installed successfully or not. I could create databases and tables, but when I tried to insert values into tables, it gave me a error says Invalid configuration of tez jars, tez.lib.uris is not defined in the configuration,  I was super confused by it, because I didn't even install tez, I thought it will use Mapreduce as its excution engine. By the way, does anyone know where the real hive-site.xml is at? I want to change the excution engine, but I couldn't find the parameter on the CM's website. ... View more
