Litchy Soong created ARROW-10555:
------------------------------------
Summary: Java API get negative messageLength
Key: ARROW-10555
URL: https://issues.apache.org/jira/browse/ARROW-10555
Project: Apache Arrow
Issue Type: Bug
Affects Versions: 1.0.1
Reporter: Litchy Soong
when I call ArrowStreamReader.vectorSchemaRoot(),
{{: (-520103681 < 0) 2020-11-09 07:09:07,033 ERROR com.intel.analytics.zoo.serving.PreProcessing - Error stack trace java.base/java.nio.

{{com.intel.analytics.zoo.shaded.arrow.vector.ipc.ArrowReader.getVectorSchemaRoot(ArrowReader.java:63)}}
{{}}
{{}}
{{The messageLength is negative, code is in MessageSerializer.java}}
{{}}
messageLength = MessageSerializer.bytesToInt(buffer.array());{{}}
{{}}
{{}}
{{and error is raised in }}
{{}}
ByteBuffer messageBuffer = ByteBuffer.allocate(messageLength);{{}}
{{}}
I tried to use minimal reproduce code to reproduce the error but I could not reproduce it. So *any ideas that when can it get negative messageLength*? This error occurs occasionally in my program.
