what is the most stable version of Impala ?

I use impala version 2.7.0 whhich i am not finding good and stable. the people from other team are using 2.3.0 version . same query runs on 2.3.0 but on 2.7.0 it goes memory out or takes 30 mins instead of 2 mins. 

I am loosing the confidence gradually . 

I would like to know what is the stable and more reliable PRODUCTION Impala version.

Re: what is the most stable version of Impala ?

I'm very sorry that you are having trouble with Impala after upgrading. Your frustration is understandable.

 

Our desire is certainly that the latest verison is always the most stable. Sometimes we have to make difficult tradeoffs to move the project forward and accept the risk of regressions.

 

Based on your description I'm guessing some of your queries had plan changes. We'd be happy to help you get to the bottom of it if you are willing to provide query profiles.
