URL: https://issues.apache.org/jira/browse/HIVE-19392
Project: Hive
Issue Type: Bug
Components: SQL

Reporter: John Doe
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.
