singqwe opened a new issue #9744: URL: https://github.com/apache/druid/issues/9744
I am trying to test my custom aggregator using the druid binaries from quickstart tutorial which writes data in base64 using the [writeBinary](https://fasterxml.github.io/jackson-core/javadoc/2.2.0/com/fasterxml/jackson/core/JsonGenerator.html#writeBinary(byte[])) method of jackson library, but when I try to aggregate using query, I get the BufferOverflowException: `{"error":"Unknown exception","errorMessage":"java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.nio.BufferOverflowException","errorClass":"java.lang.RuntimeException","host":"localhost:8083"` The logs in broker.log file are: `org.apache.druid.query.QueryInterruptedException:
