Subject [GitHub] carbondata issue #1540: [CARBONDATA-1784] clear column group code
Date Wed, 22 Nov 2017 08:30:57 GMT
Github user zzcclp commented on the issue:
    @chenliang613 , it seems there are many places about column group need to be removed,
for example:
    in TableNewProcessor.process():
    `checkColGroupsValidity(cm.columnGroups, allColumns, highCardinalityDims)`
    `updateColumnGroupsInFields(cm.columnGroups, allColumns)`
    Method 'checkColGroupsValidity' and 'updateColumnGroupsInFields' also can be removed.
    Method 'CarbonDDLSqlParser.updateColumnGroupsInField' also can be removed.
    Suggestion: in CarbonDDLSqlParserprepareTableModel, we can throw an exception when user
define 'column_groups' in TBLPROPERTIES.
