AFAIK, there is no easy way to figure out which rows fail to insert given the current implemention of Impala Kudu integration. A related jira for this is 'https://issues.apache.org/jira/browse/IMPALA-4416'. Now you can check the 'NumRowErrors' metric from Impala's query profile. But that only shows the count of failed rows.
