Ji Liu created ARROW-6145: ----------------------------- Summary: [Java] UnionVector created by MinorType#getNewVector could not keep field type info properly Key: ARROW-6145 URL: https://issues.apache.org/jira/browse/ARROW-6145 Project: Apache Arrow Issue Type: Bug Components: Java Reporter: Ji Liu Assignee: Ji Liu
When I worked for other items, I found {{UnionVector}} created by {{VectorSchemaRoot#create(Schema schema, BufferAllocator allocator)}} could not keep field type info properly. For example, if we set metadata in {{Field}} in schema, we could not get it back by {{UnionVector#getField}}. This is mainly because {{MinorType.Union.getNewVector}} did not pass {{FieldType}} to vector and {{UnionVector#getField}} create a new {{Field}} which cause inconsistent. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
