Description

This is a variation of DRILL-3705 with the difference of drill behavior when hitting OOM condition.

Query runs out of memory during execution and remains in "CANCELLATION_REQUESTED" state until drillbit is bounced.
Client (sqlline in this case) never gets a response from the server.

Reproduction details:
Single node drillbit installation.
DRILL_MAX_DIRECT_MEMORY="8G"
DRILL_HEAP="4G"

Run this query on TPCDS SF100 data set

SELECT SUM(ss.ss_net_paid_inc_tax) OVER (PARTITION BY ss.ss_store_sk) AS TotalSpend FROM store_sales ss WHERE ss.ss_store_sk IS NOT NULL ORDER BY 1 LIMIT 10;

• is depended upon by: DRILL-3317 when ProtobufLengthDecoder couldn't allocate a new DrillBuf, this error is just logged and nothing else is done
• is duplicated by: DRILL-3119 Query stays in "CANCELLATION_REQUESTED" status in UI after OOM of Direct buffer memory
• is related to: DRILL-3241 Query with window function runs out of direct memory and does not report back to client that it did
