-----------------------------------------

             Summary: Kudu duplicate key count can be off
                 Key: IMPALA-7007
                 URL: https://issues.apache.org/jira/browse/IMPALA-7007
             Project: IMPALA
          Issue Type: Bug
            Reporter: Balazs Jeszenszky


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}
