Deneche A. Hakim created ARROW-307:
--------------------------------------
Summary: UnionListWriter does not behave properly when multiple
lists are written in the same list
Key: ARROW-307
URL: https://issues.apache.org/jira/browse/ARROW-307
Project: Apache Arrow
Issue Type: Bug
Components: Java - Vectors
Reporter: Deneche A. Hakim
if you run the following code:
{code}
ListVector listVector = new ListVector("list", allocator, null);
listVector.allocateNew();
UnionListWriter listWriter = new UnionListWriter(listVector);
listWriter.start();
listWriter.startList();
listWriter.list("a").startList();
listWriter.list("a").bigInt().writeBigInt(1);
listWriter.list("a").bigInt().writeBigInt(2);
listWriter.list("a").bigInt().writeBigInt(3);
listWriter.list("a").endList();
listWriter.list("a").startList();
listWriter.list("a").bigInt().writeBigInt(4);
listWriter.list("a").bigInt().writeBigInt(5);
listWriter.list("a").endList();
listWriter.endList();
listWriter.end();
listWriter.setValueCount(1);
{code}
listVector will contain:
{noformat}
[{"a":[1,2,3,4,5]}]
{noformat}
Instead of
{noformat}
[{"a":[1,2,3],[4,5]}]
{noformat}
