Subject [jira] [Created] (ORC-313) Missing checks on SubType count of LIST and MAP types
Date Sat, 03 Mar 2018 09:20:00 GMT
Quanlong Huang created ORC-313:

             Summary: Missing checks on SubType count of LIST and MAP types
                 Key: ORC-313
                 URL: https://issues.apache.org/jira/browse/ORC-313
             Project: ORC
          Issue Type: Bug
          Components: C++, Java, Reader
    Affects Versions: 1.4.3, 1.3.4, 1.2.3, 1.1.2, 1.0.0
            Reporter: Quanlong Huang
         Attachments: ill_types.orc

When converting proto::Type to TypeImpl, we need to check that LIST and MAP types have a correct
number of subtypes. Otherwise, it will lead to later errors in the c++ reader.

A file with ill types is attached.

The java reader also has this problem and throws an IndexOutOfBoundsException immediately:
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0
