required in IPC streams even when empty
Steven Fackler created ARROW-6040:
-------------------------------------
Summary: [Java] Dictionary entries are required in IPC streams even when empty
Key: ARROW-6040
URL: https://issues.apache.org/jira/browse/ARROW-6040
Project: Apache Arrow
Issue Type: Bug
Components: Java
Reporter: Steven Fackler
Java's ArrowReader requires that dictionaries are sent in an IPC stream: [https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/ipc/ArrowReader.java#L196-L200].
However, as noted in ARROW-6006, that is not required if the stream contains no values.
