Change subject: IMPALA-11237: Preserve the behavior of CONCAT_WS() before IMPALA-8891 ...................................................................... IMPALA-11237: Preserve the behavior of CONCAT_WS() before IMPALA-8891 This patch preserves the behavior of CONCAT_WS() before IMPALA-8891 by introducing a flag of 'concat_ws_return_null_if_any_is_null', which is set to false by default. Specifically, if 'concat_ws_return_null_if_any_is_null' is set to true when the Impala daemon is started, CONCAT_WS() will return NULL as long as any of the argument values is NULL, which corresponds to the behavior before IMPALA-8891. Testing: - Added an E2E test to verifiy the behavior before IMPALA-8891 could be preserved once the flag above is set to true when the Impala daemon is started.
