--------------------------------------

             Summary: Casting strings to integers in HPL/SQL differs from Hive behavior
                 Key: HIVE-17028
                 URL: https://issues.apache.org/jira/browse/HIVE-17028
             Project: Hive
          Issue Type: Bug
          Components: hpl/sql
            Reporter: Carter Shanklin


This bug is part of a series of issues and surprising behavior I encountered writing a reporting
script that would aggregate values and give rows different classifications based on an the
aggregate. Addressing some or all of these issues would make HPL/SQL more accessible to newcomers.

In HPL/SQL: cast('10.0' as integer); results in:
Unhandled exception in HPL/SQL
java.lang.NumberFormatException: For input string: "10.0"
        at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
        at java.lang.Long.parseLong(Long.java:589)
        at java.lang.Long.parseLong(Long.java:631)
        at org.apache.hive.hplsql.Var.cast(Var.java:181)

In Hive:
hive> select cast('10.0' as integer);
10
Time taken: 4.563 seconds, Fetched: 1 row(s)
hive> select cast('10.3' as integer);
10
