--------------------------------------
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: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
