Hi, What are the key areas we need to check in the explain plan generated in Hive? I have checked the documentation, it's not detailed about the above question. https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Explain I have similar kind of question asked in our forum, which is unanswered. http://mail-archives.apache.org/mod_mbox/hive-user/201107.mbox/%3CCAAG3+BGHadR65FnR5udmGP9=QcriHuubnR8WR-VbxczdOhA=e...@mail.gmail.com%3E
In summary, how we can distinguish a good/bad plan ? Thanks for your help. -- Thanks, Pandeeswaran
