Hive set commands, syntax help


#1

How to get help on hive set commands syntax, during exam?
I couldnt find them in hive manuals/wiki.
How to view them in hive shell?

hive> SET hive.cli.print.header=true;
hive> SET mapred.reduce.tasks=32;
hive> SET hive.enforce.bucketing=true;
hive> SET hive.cli.print.current.db=true;

Which exam are you preparing for? Most people do not bother about these settings while attempting CCA175

I want to see the headers of the tables in Hive. Preparing for CCA175.
