> Apache Thrift 0.9.2 was released recently (https://thrift.apache.org/download). It has a fix for THRIFT-2660 which can cause HS2 (tcp mode) and Metastore processes to go OOM on getting a non-thrift request when they use SASL transport. The reason:
> {code}
>   protected SaslResponse receiveSaslMessage() throws TTransportException {
>     underlyingTransport.readAll(messageHeader, 0, messageHeader.length);
>     byte statusByte = messageHeader[0];
>     byte[] payload = new byte[EncodingUtils.decodeBigEndian(messageHeader, STATUS_BYTES)];
>     underlyingTransport.readAll(payload, 0, payload.length);
>     NegotiationStatus status = NegotiationStatus.byValue(statusByte);
>     if (status == null) {
>       sendAndThrowMessage(NegotiationStatus.ERROR, "Invalid status " + statusByte);
>     } else if (status == NegotiationStatus.BAD || status == NegotiationStatus.ERROR) {
>       try {
>         String remoteMessage = new String(payload, "UTF-8");
>         throw new TTransportException("Peer indicated failure: " + remoteMessage);
>       } catch (UnsupportedEncodingException e) {
>         throw new TTransportException(e);
>       }
>     }
> {code}
> Basically since there are no message format checks / size checks before creating the byte array, on getting a non-SASL message this creates a huge 
> byte array from some garbage size.
> For HS2, an attempt was made to fix it here: HIVE-6468, which never went in.  I think for 0.15.0 it's best to upgarde to Thrift 0.9.2.
