Description

The following impala-shell snippet looks odd because of the case-sensitivity of REPLACE: the column header would return 'z' if fed back into impala-shell, but the value is 't' because 'T' is not the same as 't' in REPLACE:

[localhost:21000] > select replace('t','T','z');
Query: select replace('t','T','z')
+------------------------+
| replace('t', 't', 'z') |
+------------------------+
| t                      |
+------------------------+
