Jason Dere created HIVE-11449:
---------------------------------
Summary: HybridHashTableContainer should throw exception if not
enough memory to create the hash tables
Key: HIVE-11449
URL: https://issues.apache.org/jira/browse/HIVE-11449
Project: Hive
Issue Type: Bug
Components: Query Processor
Reporter: Jason Dere
Assignee: Jason Dere
Currently it only logs a warning message:
{code}
public static int calcNumPartitions(long memoryThreshold, long dataSize, int
minNumParts,
int minWbSize, HybridHashTableConf nwayConf) throws IOException {
int numPartitions = minNumParts;
if (memoryThreshold < minNumParts * minWbSize) {
LOG.warn("Available memory is not enough to create a
HybridHashTableContainer!");
}
{code}
Because we only log a warning, processing continues and hits a hard-to-diagnose
error (log below also includes extra logging I added to help track this down).
We should probably just fail the query a useful logging message instead.
