gatorsmile f42eaf42bd [SPARK-14085][SQL] Star Expansion for Hash ... #### What changes were proposed in this pull request? This PR is to support star expansion in hash. For example, ```SQL val structDf = testData2.select("a", "b").as("record") structDf.select(hash($"*") ``` In addition, it refactors the codes for the rule `ResolveStar` and fixes a regression for star expansion in group by when using SQL API. For example, ```SQL SELECT * FROM testData2 group by a, b ``` cc cloud-fan Now, the code for star resolution is much cleaner. The coverage is better. Could you check if this refactoring is good? Thanks! #### How was this patch tested? Added a few test cases to cover it. Author: gatorsmile <gatorsmile@gmail.com> Closes #11904 from gatorsmile/starResolution.		2016-03-24 11:13:36 +08:00
