Hello  I'm new to the community and to cloudera/big data in general,    I am having issues with hive performance I have for example a table of 600 records and when I use a select * it runs in .05 seconds but if I use for example a count(*) or any function it runs in like 17 seconds, do any have any tip or trick to check performance or what parameter to check/modify in order to improve this execution time?   My enviroment are CDH 6.1.0 withHive 2.1.1-cdh6.1.0   Thank you in advance    Ulises Rangel ...
