Description

The C++ reader currently doesn't recognize the UNSTABLE-PRE-2.0 version which is added in ORC-49 in the Java client.

To be specifit, when reading an ORCv2 file, the C++ reader gets "1.9999" as the version.

$ tools/src/orc-metadata decimal64_v2.orc
Warning: ORC file decimal64_v2.orc was written in an unknown format version 1.9999
{ ...
  "format": "1.9999", "writer version": "ORC-135", "software version": "ORC Java",
  ...
}

The Java client can read the version as expected

$ java -jar orc-tools-1.8.0-SNAPSHOT-uber.jar meta decimal64_v2.orc
...
File Version: UNSTABLE-PRE-2.0 with ORC_135 by ORC Java
...
