Patch Set 1: (4 comments) Thanks, Todd. Can you ref IMPALA-4134 in the commit comment? http://gerrit.cloudera.org:8080/#/c/4670/1/be/src/exec/kudu-table-sink.cc File be/src/exec/kudu-table-sink.cc: PS1, Line 176: SetString I assume this doesn't result in any more copying than we had before? PS1, Line 225: // TODO: instead of adding them here and subtracting errors in CheckForErrors, : // would it be better to _set_ the value to the total number of written rows : // minus the errors minus the current buffer size? Yeah, this is a bit weird as it is. I'd vote to compute this as you described in CheckForErrors even though that method name doesn't really hint it'll update this counter, but a brief mention in the header comment should be OK. I don't actually us use this value for non-HDFS tables besides something that looks like legacy code in impala-beeswax-server.
