Hi Experts,
Hope you all are doing well. I want to take some expert opinion here: We are switching from Oracle to Hadoop due to slow performance with Oracle DB, built a universe with Cloudera Simba ODBC connections scheduled a report expecting a faster performance compare to Oracle DB but the report took more than 2 hours, took the same query and ran in HUE SQL editor the result got back in less than 2 mins
We tested in DEV, TEST, & PROD, & also tried switching to JDBC connection little improvement in performance, we feel its the network's latency issue. Points to note here that our Hadoop servers and BO servers are in two different locations NCAL and SCAL, we have 3.5 million records to pull
I am looking for some tested advice here on this issue if anyone has already faced such issue
Regards,
Ahmed
Hello,
If the data source is Hadoop than you should use Apache Simba JDBC \ODBC. Please check our supported platform.
I hope this could help.
Thanks,

Hello,
What's the version of BO you are using?
What's the version of Hadoop (Hive1 or Hive2)?
What is the reason you are using Cloudera Simba ODBC\JDBC vs Apache Simba JDBC \ODBC
If you have Hadoop than you should use Apache Simba JDBC \ODBC
Thanks,
Sonet
