Marco Battaglia created KNOX-720:
------------------------------------
Summary: Sockets remain in CLOSE_WAIT using
org.apache.hadoop.gateway.shell.Hadoop
Key: KNOX-720
URL: https://issues.apache.org/jira/browse/KNOX-720
Project: Apache Knox
Issue Type: Bug
Components: ClientDSL
Affects Versions: 0.7.0
Reporter: Marco Battaglia
The class org.apache.hadoop.gateway.shell.Hadoop used to connect to knox
doesn't close opened socket.
The "shutdown" method of org...shell.Hadoop doesn't call client.close() and
this produces too much permanent CLOSE_WAIT sockest.
Suggestion:
public void shutdown() throws InterruptedException {
-
+ closeClient();
}
public boolean shutdown( long timeout, TimeUnit unit ) throws
InterruptedException {
- executor.shutdown();
+ closeClient();
return executor.awaitTermination( timeout, unit );
}
+
+ private void closeClient(){
+ executor.shutdownNow();
+ if(client!=null){
+ client.close();
+ }
+ }
