[jira] [Created] (HAMA-482) LocalBSPRunner cannot deliver multiple
messages to the same peer
LocalBSPRunner cannot deliver multiple messages to the same peer
-----------------------------------------------------------------
Key: HAMA-482
URL: https://issues.apache.org/jira/browse/HAMA-482
Project: Hama
Issue Type: Bug
Reporter: Tommaso Teofili
Assignee: Tommaso Teofili
Fix For: 0.4.0
the line 331 of LocalBSPRunner contains a warning which may result in bugs with multiple messages.
In fact
{code}
LinkedList<BSPMessage> msgs = localOutgoingMessages.get(peerName);
{code}
is trying to get a List of BSPMessage instances from a localOutgoingMessages of type {code}HashMap<InetSocketAddress, LinkedList<BSPMessage>>{code}.
It seems to me there is problem as peerName is a String, not a InetSocketAddress and in fact my debugging session highlighted that get() method to result always to return a null object.
The quick fix seems to be putting the lines 337-341 :
{code}
InetSocketAddress inetSocketAddress = socketCache.get(peerName);
if (inetSocketAddress == null) {
inetSocketAddress = BSPNetUtils.getAddress(peerName);
socketCache.put(peerName, inetSocketAddress);
}
{code}
upmost in the method and then call
{code}
LinkedList<BSPMessage> msgs = localOutgoingMessages.get(inetSocketAddress);
{code}
This was highlighted when dealing with multiple messages sent to a same peer in local mode (only the last msg was actually stored in the outGoingMessages item for that peer).

Hudson commented on HAMA-482:
-----------------------------
Integrated in Hama-Nightly #372 (See [https://builds.apache.org/job/Hama-Nightly/372/])
[HAMA-482] - InetSocketAddress is initialized first by peerName and then used accordingly with localOutgoingMessages
