Hi Alex, Thanks for your reply. The jira link you have shared seems to be a pretty old one and there are some comments saying this may be available in impala 2.2 onwards but as per my information cdh 5.5.4 has impala 2.3. it seems this issue was raised 4 years back but still not been implented yet as we are using microstaregy as our bI tool, so doing cross joins with the large tables are not a feasible solution in it. Is this a fundamental constaraint in impala or it may come in a later impala version? it will be great if you can give an hint in which impala version or cdh version this functionality may be valuable. it will be helpfull for sure to the future users.

Hi All, I am able to run the below query in hive but not in impala. I am using CDH 5.5.4 Is it possible in impala or not? QUERY: Select count(distinct(concat(c1,c2))) as Key, sum(distinct(c3)) as Val FROM test; In HIve it is successfully executed but in impala i am getting the below error. AnalysisException: all DISTINCT aggregate functions need to have the same set of parameters as count(DISTINCT (concat(c1,c2))); deviating function: sum(DISTINCT (c3)) Any suggesstions on how to do it in a better way if not possible in impala will be helpful. thanks Nisith

Finally Able to debug and fix the issue. The Issue was with the installation as one of the data nodes are having older version of parquet Jars(5.2 cdh distribution). After replacing the jars with the current version jars it was working fine.
