Impala New Release Update FAQ

[#1]

Hi Team,

Greetings!

We are using Impala(Version 2.12.0) for running our queries and are keen to know when you are going to launch the upgrade which will overcome problem of count(distinct) for different fields at same level of aggregation.

Please reply asap.In case of any doubts please reach out to me 

Regards,

Sanchay Garg

@ImpalaUpgrades Are you using 

set APPX_COUNT_DISTINCT=true;

adding this prior to the query run should solve this.

Hi ,

This is giving me the same results as ndv() and not count(distinct)

Please guide us on the same.

I can't techically give you a release commitment, but it looks like it should be in CDH 6.1 at this point given that it was merged into Apache Impala in advance of the Apache Impala 3.1.0 release (see https://issues.apache.org/jira/browse/IMPALA-110) and has gone through most of our internal testing process since then.
