Subject Erroir when using HPL/SQL function in Hive CTL
Date Thu, 19 Jul 2018 10:12:40 GMT
Hi All,

I follow the steps in http://www.hplsql.org/udf run hplsql function in Hive
CTL. However it have the error and I cannot find ideas to fix it.

hive> add jar /usr/local/hive/lib/hive-hplsql-2.3.3.jar;
Added [/usr/local/hive/lib/hive-hplsql-2.3.3.jar] to class path
Added resources: [/usr/local/hive/lib/hive-hplsql-2.3.3.jar]
hive> add jar /usr/local/hive/lib/antlr-runtime-3.5.2.jar;
Added [/usr/local/hive/lib/antlr-runtime-3.5.2.jar] to class path
Added resources: [/usr/local/hive/lib/antlr-runtime-3.5.2.jar]
hive> add file /usr/local/hive/conf/hplsql-site.xml;
Added resources: [/usr/local/hive/conf/hplsql-site.xml]
hive> add file /usr/local/hive/script/hplsqlrc;
Added resources: [/usr/local/hive/script/hplsqlrc]
hive> CREATE TEMPORARY FUNCTION hplsql AS 'org.apache.hive.hplsql.Udf';
OK
Time taken: 0.01 seconds
hive> SELECT hplsql('hello(:1)', name) FROM users;
OK
Configuration file: file:/usr/local/hive/conf/hplsql-site.xml
Parser tree: (program (block (stmt (expr_stmt (expr (expr_func (ident
hello) ( (expr_func_params (func_param (expr (expr_atom (ident :1)))))
)))))))
INCLUDE file error: File 'hplsql_locals.sql' does not exist
Ln:1 Function not found: hello
NULL
Time taken: 0.549 seconds, Fetched: 1 row(s)

How can I fix the problem? Thank you!
Below is the configuration of 'hplsql-site.xml.' Here I didn't use
hiveserver2. I'm wondering if the hiveserve2 is required to be defalt
connection.
