Balazs Jeszenszky updated IMPALA-7007:
--------------------------------------
    Affects Version/s: Impala 2.12.0

> Kudu duplicate key count can be off
> -----------------------------------
>
>                 Key: IMPALA-7007
>                 URL: https://issues.apache.org/jira/browse/IMPALA-7007
>             Project: IMPALA
>          Issue Type: Bug
>    Affects Versions: Impala 2.12.0
>            Reporter: Balazs Jeszenszky
>            Priority: Major
>
> After inserting TPC-H data into Kudu by doing:
> {code}
> insert into lineitem select * from PARQUETIMPALA500.LINEITEM
> {code}
> , the query profile contains this error:
> {code}
> Errors: Key already present in Kudu table 'impala::kudu_impala_500.LINEITEM'. (1 of -1831809966 similar)
> {code}
> Clearly, the count is off here. Also, it seems this issue can trigger a DCHECK on debug builds. The accompanying log line in that case is:
> {code}
> F0507 09:46:12.673912 29258 error-util.cc:148] Check failed: log_entry.count > 0 (-1831809966 vs. 0) 
> {code}
