> Project: Hive
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.0.0
> Reporter: John Doe
> Assignee: Andrew Sherman
> Priority: Minor
>
> In DataInputByteBuffer$Buffer class, the fields bidx and buffers, etc are
> unsynchronized when used in read() and reset() function. In certain
> circumstances, e.g., the reset() is invoked in a loop, the unsynchronized
> bidx and buffers can trigger a concurrency bug.
> This bug also shows in
> [Hadoop-15429|https://issues.apache.org/jira/browse/HADOOP-15429].
