Martin Illecker updated HAMA-812:
---------------------------------
Attachment: HAMA-812.patch
Added check for local mode in BSPJobClient.close to avoid
IllegalArgumentException: not a proxy instance.
{code}
public synchronized void close() throws IOException {
String masterAdress = this.getConf().get("bsp.master.address");
if (masterAdress != null && !masterAdress.equals("local")) {
RPC.stopProxy(jobSubmitClient);
}
}
{code}
Similar check was in BSPJobClient.init before, where the proxy instance is
added. In local mode there is no proxy instance in jobSubmitClient.
{code}
public void init(Configuration conf) throws IOException {
String masterAdress = conf.get("bsp.master.address");
if (masterAdress != null && !masterAdress.equals("local")) {
this.jobSubmitClient = (JobSubmissionProtocol) RPC.getProxy(
JobSubmissionProtocol.class, HamaRPCProtocolVersion.versionID,
BSPMaster.getAddress(conf), conf,
NetUtils.getSocketFactory(conf, JobSubmissionProtocol.class));
} else {
LOG.debug("Using local BSP runner.");
this.jobSubmitClient = new LocalBSPRunner(conf);
}
}
{code}
