    Description

      After inserting TPC-H data into Kudu by doing:

      insert into lineitem select * from PARQUETIMPALA500.LINEITEM
      

      , the query profile contains this error:

      Errors: Key already present in Kudu table 'impala::kudu_impala_500.LINEITEM'. (1 of -1831809966 similar)
      

      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:

      F0507 09:46:12.673912 29258 error-util.cc:148] Check failed: log_entry.count > 0 (-1831809966 vs. 0)
