[jira] [Updated] (HIVE-6094) add UDF array_rcontains for ARRAY

     [ https://issues.apache.org/jira/browse/HIVE-6094?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kostiantyn Kudriavtsev updated HIVE-6094:
-----------------------------------------

    Description: 
Add new UDF array_rcontains for Array<String> to check if array contains string by regexp

For example, we have array of strings in the column FRIENDS, then we can check for if particular person has .+Smith in friends:
array_rcontains(FRIENDS, '.+Smith')
   

  was:

For example, we have array of strings in the column FRIENDS, then we can check for if particular person has .+Smith in friends:
array_rcontains(FRIENDS, '.+Smith', 'i')
where 'i' means case sensitive, this is discussable option
