Key: HIVE-16174
URL: https://issues.apache.org/jira/browse/HIVE-16174
Project: Hive
Issue Type: Bug
Components: Query Planning
Affects Versions: 2.2.0
Reporter: yunfei liu
Assignee: yunfei liu
Priority: Minor
In Driver#compileInternal method (as the code snippet below ), we need to
update MetricsConstant.WAITING_COMPILE_OPS metric correctly before return if
lock can not be acquired.
{code}
Metrics metrics = MetricsFactory.getInstance();
if (metrics != null) {
metrics.incrementCounter(MetricsConstant.WAITING_COMPILE_OPS, 1);
}
final ReentrantLock compileLock = tryAcquireCompileLock(isParallelEnabled,
command);
if (compileLock == null) {
return ErrorMsg.COMPILE_LOCK_TIMED_OUT.getErrorCode();
}
{code}
