[~stigahuang] [~csringhofer] I wrote the udtf usage scenario and how to create the query plan.

There is an Epic tracking this feature: IMPALA-9521. Maybe we can start from some simple ones like IMPALA-9522, IMPALA-9523, IMPALA-9524, IMPALA-9525, IMPALA-9526. Before jumping into coding, it'd nice to have a design doc for discussion. > SUPPORT user-defined table functions (UDTFs) > > > Key: IMPALA-11527 > URL: https://issues.apache.org/jira/browse/IMPALA-11527 > Project: IMPALA > Issue Type: New Feature >Reporter: gaoxiaoqing >Assignee: gaoxiaoqing >Priority: Major > > Currently, Impala does not support user-defined table functions (UDTFs), some > Data Analysis Scenario need this feature such as funnel analysis, session > analysis and so on.
