Examples with ContainerUpdateType org.apache.hadoop.yarn.api.records.ContainerUpdateType used on opensource projects

Example 1 with ContainerUpdateType

use of org.apache.hadoop.yarn.api.records.ContainerUpdateType in project hadoop by apache.

the class AMRMClientImpl method createUpdateList.

private List<UpdateContainerRequest> createUpdateList() {
    List<UpdateContainerRequest> updateList = new ArrayList<>();
    for (Map.Entry<ContainerId, SimpleEntry<Container, UpdateContainerRequest>> entry : change.entrySet()) {
        Resource targetCapability = entry.getValue().getValue().getCapability();
        ExecutionType targetExecType = entry.getValue().getValue().getExecutionType();
        ContainerUpdateType updateType = entry.getValue().getValue().getContainerUpdateType();
        int version = entry.getValue().getKey().getVersion();
        updateList.add(UpdateContainerRequest.newInstance(version, entry.getKey(), updateType, targetCapability, targetExecType));
    }
    return updateList;
}

Example 2 with ContainerUpdateType

use of org.apache.hadoop.yarn.api.records.ContainerUpdateType in project hadoop by apache.

the class RMServerUtils method validateAndSplitUpdateResourceRequests.

/**
   * Check if we have:
   * - Request for same containerId and different target resource.
   * - If targetResources violates maximum/minimumAllocation.
   * @param rmContext RM context.
   * @param request Allocate Request.
   * @param maximumAllocation Maximum Allocation.
   * @param updateErrors Container update errors.
