David Li created ARROW-8665: ------------------------------- Summary: [Java] DenseUnionWriter#setPosition fails with NullPointerException Key: ARROW-8665 URL: https://issues.apache.org/jira/browse/ARROW-8665 Project: Apache Arrow Issue Type: Bug Components: Java Affects Versions: 0.17.0 Reporter: David Li
The writer always iterates through all BaseWriters, and an array of 128 BaseWriters is allocated. So if you do not have 128 typeIds and do not touch all of them, setPosition will give you an exception. -- This message was sent by Atlassian Jira (v8.3.4#803005)
