Description

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...
