Description

Preconditions:
1. Impala 2.2 is running;
2. impala-shell is opened;

Steps to reproduce:
1. Enter in the command line:

select case when notnullvalue('true') then 'PASS' end;

(it's described in Cloudera documentation
http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/impala_conditional_functions.html)

Actual result:

select case when notnullvalue('true') then 'PASS' end;
Query: select case when notnullvalue('true') then 'PASS' end
ERROR: AnalysisException: default.notnullvalue() unknown

Expected result:

case when notnullvalue('true') then 'pass' end

PASS

P.S.: Same conditional function 'nonnullvalue' works
