-------------------------------------------------------------
[[email protected]] Happy to hear that .
I saw this in kylin2.2 :
{code:java}
TblColRef(TableRef table, ColumnDesc column) {
checkArgument(table.getTableDesc().getIdentity().equals(column.getTable().getIdentity()));
this.table = table;
this.column = column;
}
{code}
I had merge this into our kylin (v1.6) , I'm not sure if that can resolve the
problem.
