> 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.
