[jira] [Created] (HIVE-13500) Launching big queries fails with Out
of Memory Exception
Rajat Khandelwal created HIVE-13500:
---------------------------------------
Summary: Launching big queries fails with Out of Memory Exception
Key: HIVE-13500
URL: https://issues.apache.org/jira/browse/HIVE-13500
Project: Hive
Issue Type: Bug
Reporter: Rajat Khandelwal
Assignee: Rajat Khandelwal
There is a code snipped in Driver class in compile method:
{noformat}
if (conf.getBoolVar(ConfVars.HIVE_LOG_EXPLAIN_OUTPUT) ||
conf.isWebUiQueryInfoCacheEnabled()) {
String explainOutput = getExplainOutput(sem, plan, tree);
if (explainOutput != null) {
if (conf.getBoolVar(ConfVars.HIVE_LOG_EXPLAIN_OUTPUT)) {
LOG.info("EXPLAIN output for queryid " + queryId + " : "
+ explainOutput);
}
if (conf.isWebUiQueryInfoCacheEnabled()) {
queryDisplay.setExplainPlan(explainOutput);
}
}
}
{noformat}
This is the stack trace

Now, in plain English, in the compile phase, hive is trying to generate explain output and set that output in the query display. Generating the explain output fails with OOM.
I propose that setting of the explain output in query display be made optional, so that queries can still launch.
