Description

I'm probably doing something wrong here, but I can't figure it out.

My ApplicationMaster is sending an AllocateRequest with ContainerIds to release. My ResourceManager logs say:

2011-10-25 10:02:52,236 WARN resourcemanager.RMAuditLogger (RMAuditLogger.java:logFailure(207)) - USER=criccomi IP=127.0.0.1 OPERATION=AM Released Container TARGET=FifoScheduler RESULT=FAILURE DESCRIPTION=Trying to release container not owned by app or with invalid id PERMISSIONS=Unauthorized access or invalid container APPID=application_1319485153554_0028 CONTAINERID=container_1319485153554_0028_01_000003

The container ID is valid, as is the app id:

./application_1319485153554_0028/container_1319485153554_0028_01_000006/stdout

The containers are still running.

My code to start a container, and then to release it:

  // ugi = UserGroupInformation.getCurrentUser
  // security is not enabled
  def startContainer(packagePath: Path, container: Container, ugi: UserGroupInformation, env: Map[String, String], cmds: String*) {
    info("%s starting container %s %s %s %s %s" format (appAttemptId, packagePath, container, ugi, env, cmds))
    // connect to container manager (based on similar code in the ContainerLauncher in Hadoop MapReduce)
    val contToken = container.getContainerToken
    val address = container.getNodeId.getHost + ":" + container.getNodeId.getPort
    var user = ugi

    if (UserGroupInformation.isSecurityEnabled) {
      debug("%s security is enabled" format (appAttemptId))
      val hadoopToken = new Token[ContainerTokenIdentifier](contToken.getIdentifier.array, contToken.getPassword.array, new Text(contToken.getKind), new Text(contToken.getService))
      user = UserGroupInformation.createRemoteUser(address)
      user.addToken(hadoopToken)
      info("%s changed user to %s" format (appAttemptId, user))
    }

    val containerManager = user.doAs(new PrivilegedAction[ContainerManager] {
      def run(): ContainerManager = {
        return YarnRPC.create(conf).getProxy(classOf[ContainerManager], NetUtils.createSocketAddr(address), conf).asInstanceOf[ContainerManager]
      }
    })

    // set the local package so that the containers and app master are provisioned with it
    val packageResource = Records.newRecord(classOf[LocalResource])
    val packageUrl = ConverterUtils.getYarnUrlFromPath(packagePath)
    val fileStatus = packagePath.getFileSystem(conf).getFileStatus(packagePath)

    packageResource.setResource(packageUrl)
    packageResource.setSize(fileStatus.getLen)
    packageResource.setTimestamp(fileStatus.getModificationTime)
    packageResource.setType(LocalResourceType.ARCHIVE)
    packageResource.setVisibility(LocalResourceVisibility.APPLICATION)

    // start the container
    val ctx = Records.newRecord(classOf[ContainerLaunchContext])
    ctx.setEnvironment(env)
    ctx.setContainerId(container.getId())
    ctx.setResource(container.getResource())
    ctx.setUser(user.getShortUserName())
    ctx.setCommands(cmds.toList)
    ctx.setLocalResources(Collections.singletonMap("package", packageResource))

    debug("%s setting package to %s" format (appAttemptId, packageResource))
    debug("%s setting context to %s" format (appAttemptId, ctx))

    val startContainerRequest = Records.newRecord(classOf[StartContainerRequest])
    startContainerRequest.setContainerLaunchContext(ctx)
    containerManager.startContainer(startContainerRequest)
  }

---

  def sendResourceRequest(requests: List[ResourceRequest], release: List[ContainerId]): AMResponse = {
    info("%s sending resource request %s %s" format (appAttemptId, requests, release))
    val req = Records.newRecord(classOf[AllocateRequest])
    req.setResponseId(requestId)
    req.setApplicationAttemptId(appAttemptId)
    req.addAllAsks(requests)
    req.addAllReleases(release)
    requestId += 1
    debug("%s RM resource request %s" format (appAttemptId, req))
    resourceManager.allocate(req).getAMResponse
  }

I have double checked that my ContainerIds are accurate, and they are.

Any idea what I'm doing wrong here?
