[jira] [Updated] (HIVE-11449) "Capacity must be a power of two"
error when HybridHashTableContainer memory threshold is too low
[ https://issues.apache.org/jira/browse/HIVE-11449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jason Dere updated HIVE-11449:
------------------------------
Summary: "Capacity must be a power of two" error when HybridHashTableContainer memory threshold is too low (was: 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

> 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.
