Review request for hive, Jason Dere and Vikram Dixit Kumaraswamy.
Bugs: HIVE-13063
https://issues.apache.org/jira/browse/HIVE-13063
Repository: hive-git
Description
-------
Create UDFS for these functions.
CHAR: convert n where n : [0, 256) into the ascii equivalent as a varchar. If n
is less than 0 or greater than 255, return the empty string. If n is 0, return
null.
REPLACE: replace all substrings of 'str' that match 'search' with 'rep'.
Example. SELECT REPLACE('Hack and Hue', 'H', 'BL');
Equals 'BLack and BLue'"

Testing
-------
Verified that UDFs work.
ADD JAR hdfs://c6401.ambari.apache.org:8020/tmp/hive-exec.jar;
CREATE TEMPORARY FUNCTION char_udf AS 'org.apache.hadoop.hive.ql.udf.UDFChar';
CREATE TEMPORARY FUNCTION replace_udf AS
'org.apache.hadoop.hive.ql.udf.UDFReplace';
SHOW FUNCTIONS;
DESCRIBE FUNCTION char_udf;
DESCRIBE FUNCTION replace_udf;
select char_udf(-1),
char_udf(0),
char_udf(1),
char_udf(48),
char_udf(65),
char_udf(68.12),
char_udf(32457964);
select replace_udf('', '', ''),
replace_udf(null, '', ''),
replace_udf('', null, ''),
replace_udf('', '', null),
replace_udf('Hack and Hue', 'H', 'BL'),
replace_udf('ABABrdvABrk', 'AB', 'a');
