[jira] [Created] (ARROW-10341) Arrow vector in Java(Scala) allocate byteBuffer error while read the bytes from Python pyarrow

Litchy Soong created ARROW-10341:
------------------------------------

             Summary: Arrow vector in Java(Scala) allocate byteBuffer error while read the bytes from Python pyarrow
                 Key: ARROW-10341
                 URL: https://issues.apache.org/jira/browse/ARROW-10341
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java, Python
    Affects Versions: 1.0.1, 0.17.0, 0.14.1
            Reporter: Litchy Soong


I am using scala arrow 1.0.1 and pyarrow 1.0.1

Following error occurs when scala decode the byte that encoded from python.

tried to downgrade pyarrow to 0.17.0, 0.14.1, error still exists.

This is a loop function to decode the same data repeatedly. The error occurs sometimes, after an error occurs, following code could still work correctly.
```

```
How to fix it?
