----------------------------------
Summary: Backwards-incompatible change to thrift metadata
Key: PARQUET-405
URL: https://issues.apache.org/jira/browse/PARQUET-405
Project: Parquet
Issue Type: Bug
Affects Versions: 1.8.0
Reporter: Ben Kirwin
Sometime in the last few versions, a {{isStructOrUnion}} field has been added
to the `thrift.descriptor` written to the parquet header:
{code}
{
"children": [ ... ],
"id": "STRUCT",
"structOrUnionType": "STRUCT"
}
{code}
The current release now throws an exception when that field is missing /
{{UNKNOWN}}). This makes it impossible to read back thrift data written using a
previous release.
