--------------------------------------------
Summary: ipc.Client.stop() may sleep too long to wait for all
connections
Key: HADOOP-16126
URL: https://issues.apache.org/jira/browse/HADOOP-16126
Project: Hadoop Common
Issue Type: Improvement
Components: ipc
Reporter: Tsz Wo Nicholas Sze
Assignee: Tsz Wo Nicholas Sze
{code}
//Client.java
public void stop() {
...
// wait until all connections are closed
while (!connections.isEmpty()) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
}
}
...
}
{code}
In the code above, the sleep time is 100ms. We found that simply changing the
sleep time to 10ms could improve a Hive job running time by 10x.
