@attilabukor Hi, Thank you for your comment. Yesterday, I got a comment from HaoHao about this issue. The issue not being able to create KUDU table on CDH 6.3.2 is related to remote HMS configuration in hive-site.xml KuduTable.java ( on CDH 6.3.2 ) has a logic validating if `hmsuris` is null or empty. If `hmsuris` is empty or null, it raises exception and fails. This has been fixed on master branch, but I'm not sure if this fix will be delivered with CDH 6.3.3 Can you confirm if the fix is shipped with CDH 6.3.3? Here is the bug report ticket. https://issues.apache.org/jira/browse/IMPALA-8974 Gatsby

Hi @anis016 , Glad to hear the issue got resolved after downgrading OpenJDK version. I have seen some other customers who experienced the issues with u242 version. Cheers!

Yeap, you're right

Alex, Thank you again. Subquery approach has been recommended to our team as a long term solution. However, for short-tem solution to avoid regression impact, using view with limited partitions has been selected. If I remember correctly, in MySQL `table A` data can be limited by `ON Clause` before joining so that cadidates for join can be reduced. Thank you for your valuable comment. Gatsby

@gaurang would you be open to sharing your CREATE TABLEs, CREATE VIEW and the query that has slow planning time? No need for the data, just that should be sufficient for us to understand better what's going on. Like Lars said, you are probably hitting IMPALA-4242 which explains the slow equivalence class computation, but I'd also like to understand the slow single-node planning time. Thanks!

Sure thing, I'm glad you found the culprit. 🙂

Thank you. I will check with team to set the timeout. Gatsby
