> Hi all:
>    
> when I want to change the column in hive source table and reload table in kylin,  I can not see any column in the table after reload, I restart kylin server and reload the table , the column(name is modified) appeares 
> I write a test program like this(kylin do the same thing while reloading table) :
> HiveClient client = new HiveClient();
> List<FieldSchema> fields = client.getHiveTableFields(database, table);
> \\waiting here and modify table column name
>  fields = client.getHiveTableFields(database, table);
> client.getHiveTableFields return all columns in the table at the first time, and after I modify one column and recall  client.getHiveTableFields function, it return am empty list. It will return the same list if I do not change the column name in the middle.
> I doubt maybe something error in hive metastore, any help will be appreciate...
