----------------------------------------

+1 [~prasanth_j] I think you haven't named patch correctly. You need to rename and reupload
patch to have HiveQA run on it.

> When invalid column name is specified for column statistics IndexOutOfBoundsException
is thrown. 
> {code}hive> analyze table customer_staging compute statistics for columns c_first_name,
invalid_name, c_customer_sk;
> FAILED: IndexOutOfBoundsException Index: 2, Size: 1{code}
> If the invalid column name appears at first or last then INVALID_COLUMN_REFERENCE is
thrown at query planning stage. But if the invalid column name appears somewhere in the middle
of column lists then IndexOutOfBoundsException is thrown at semantic analysis step. The problem
is with getTableColumnType() and getPartitionColumnType() methods. The following segment 
> {code}    for (int i=0; i <numCols; i++) {
>       colName = colNames.get(i);
>       for (FieldSchema col: cols) {
>         if (colName.equalsIgnoreCase(col.getName())) {
>           colTypes.add(i, new String(col.getType()));
>         }
>       }
>     }{code}
> is the reason for it. If the invalid column names appears in the middle of column list
then the equalsIgnoreCase() skips the invalid name and increments the i. Since the list is
not initialized it results in exception.
