> Affects Versions: 1.0.0

> Priority: Major
>
> Similar to the SerializationUtils.readLongBE() function reported in
> [HIVE-13397|https://issues.apache.org/jira/browse/HIVE-13397], when Instream
> is corrupted, the following loop can become infinite, too.
> {code:java}
> private void readRemainingLongs(long[] buffer, int offset, InStream input,
> int remainder,
> int numBytes) throws IOException {
> final int toRead = remainder * numBytes;
> // bulk read to buffer
> int bytesRead = input.read(readBuffer, 0, toRead);
> while (bytesRead != toRead) {
> bytesRead += input.read(readBuffer, bytesRead, toRead - bytesRead);
> }
> ...
> }
> {code}
