>                 URL: https://issues.apache.org/jira/browse/IMPALA-8152
>             Project: IMPALA
>          Issue Type: Bug
>    Affects Versions: Impala 2.12.0
>            Reporter: Alan Jackoway
>            Priority: Major
>
> We have an HBase-backed impala table, which has a string column (for the purpose of this jira, {{sCol}})
> There are records where that column is null, which we can observe with queries like {{select * from table where sCol is null limit 1}}
> However, when we run these commands, we get bad results:
> {code:sql}
> -- Returns 0
> select count(*) from table where sCol is null;
> -- Returns only rows for string values (we only have a few options in this case), no row for null
> select sCol, count(*) from table group by sCol
> {code}
> These commands work as expected on parquet-backed tables. They also do not work in Hive, where I will file a jira shortly.
