Justin created ARROW-11936: ------------------------------ Summary: Rust/Java incorrect serialization of Struct wrapped Int8Dictionary Key: ARROW-11936 URL: https://issues.apache.org/jira/browse/ARROW-11936 Project: Apache Arrow Issue Type: Bug Components: Java, Rust Affects Versions: 3.0.0 Reporter: Justin
Using rust, serialized datatype to a file with a schema of {code:java} Field { name: "val", data_type: Struct([Field { name: "val", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }]), nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }{code} Using a java client to read the serialized datatype results in a schema of {code:java} Schema<val: Struct<val: Utf8 not null> not null>{code} whilst calling ArrowFileReader.loadNextBatch() results in {code:java} Exception in thread "main" java.util.NoSuchElementExceptionException in thread "main" java.util.NoSuchElementException at java.base/java.util.ArrayList$Itr.next(ArrayList.java:1000) at org.apache.arrow.vector.VectorLoader.loadBuffers(VectorLoader.java:81) at org.apache.arrow.vector.VectorLoader.loadBuffers(VectorLoader.java:99) at org.apache.arrow.vector.VectorLoader.load(VectorLoader.java:61) at org.apache.arrow.vector.ipc.ArrowReader.loadRecordBatch(ArrowReader.java:205) at org.apache.arrow.vector.ipc.ArrowFileReader.loadNextBatch(ArrowFileReader.java:153) {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
