[jira] Updated: (HIVE-996) "describe function" throws NPE when when called on UDTF or UDAF

["Bill Jia (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-996?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bill Jia updated HIVE-996:
--------------------------

    Attachment: HIVE-894.1.patch

(1) Standard apache header added into the new files. 
(2) Codes shared. Added a new file/class SortedArrayUtils.java with two static functions - static void binaryInsert(ArrayList<Double> array, Double value, boolean ascending), and static ArrayList<Double> sortedMerge(ArrayList<Double> a1, ArrayList<Double> a2, boolean ascending, int N). 
(3) Skipped "describe max_n; and describe extended max_n" in the q files, since the tests failed.
