I included an example like that in the discussion right before this list. Now with SORTBY gone, seems like the only combination for INSERT could be CLUSTERED and SHUFFLE or NOSHUFFLE. So I prefer not to repeat the same example twice so close together. Let's see how the result looks when all is said and done. http://gerrit.cloudera.org:8080/#/c/5655/4/docs/topics/impala_insert.xml File docs/topics/impala_insert.xml: Line 67: hint_with_dashes ::= -- +SHUFFLE | -- +NOSHUFFLE <ph rev="IMPALA-4163">| -- +SORTBY(<varname>col</varname>, <varname>col</varname> ...)]</ph> > Add CLUSTERED to the list? Done. I added it under hints_with_dashes and hints_with_cstyle_comments. Not under hints_with_brackets.
