If a cluster is not in "Active", "Deleting" or "Error" state and last update of it was longer than "cleanup_time_for_incomplete_clusters" hours ago then it will be deleted automatically. (0 value means that automatic clean up is disabled). * - ``cluster_remote_threshold`` = ``70`` - (Integer) The same as global_remote_threshold, but for a single cluster. * - ``compute_topology_file`` = ``etc/sahara/compute.topology`` - (String) File with nova compute topology. It should contain mapping between nova computes and racks. * - ``coordinator_heartbeat_interval`` = ``1`` - (Integer) Interval size between heartbeat execution in seconds. Heartbeats are executed to make sure that connection to the coordination server is active. * - ``default_ntp_server`` = ``pool.ntp.org`` - (String) Default ntp server for time sync * - ``disable_event_log`` = ``False`` - (Boolean) Disables event log feature. * - ``enable_data_locality`` = ``False`` - (Boolean) Enables data locality for hadoop cluster. Also enables data locality for Swift used by hadoop. If enabled, 'compute_topology' and 'swift_topology' configuration parameters should point to OpenStack and Swift topology correspondingly. * - ``enable_hypervisor_awareness`` = ``True`` - (Boolean) Enables four-level topology for data locality. Works only if corresponding plugin supports such mode. * - ``executor_thread_pool_size`` = ``64`` - (Integer) Size of executor thread pool. * - ``global_remote_threshold`` = ``100`` - (Integer) Maximum number of remote operations that will be running at the same time. Note that each remote operation requires its own process to run. * - ``hash_ring_replicas_count`` = ``40`` - (Integer) Number of points that belongs to each member on a hash ring. The larger number leads to a better distribution. * - ``heat_enable_wait_condition`` = ``True`` - (Boolean) Enable wait condition feature to reduce polling during cluster creation * - ``heat_stack_tags`` = ``data-processing-cluster`` - (List) List of tags to be used during operating with stack. * - ``infrastructure_engine`` = ``heat`` - (String) DEPRECATED: An engine which will be used to provision infrastructure for Hadoop cluster. * - ``job_binary_max_KB`` = ``5120`` - (Integer) Maximum length of job binary data in kilobytes that may be stored or retrieved in a single operation. * - ``job_canceling_timeout`` = ``300`` - (Integer) Timeout for canceling job execution (in seconds). Sahara will try to cancel job execution during this time. * - ``job_workflow_postfix`` = - (String) Postfix for storing jobs in hdfs. Will be added to '/user//' path. * - ``memcached_servers`` = ``None`` - (List) Memcached servers or None for in process cache. * - ``min_transient_cluster_active_time`` = ``30`` - (Integer) Minimal "lifetime" in seconds for a transient cluster. Cluster is guaranteed to be "alive" within this time period. * - ``node_domain`` = ``novalocal`` - (String) The suffix of the node's FQDN. In nova-network that is the dhcp_domain config parameter. * - ``os_region_name`` = ``None`` - (String) Region name used to get services endpoints. * - ``periodic_coordinator_backend_url`` = ``None`` - (String) The backend URL to use for distributed periodic tasks coordination. * - ``periodic_enable`` = ``True`` - (Boolean) Enable periodic tasks. * - ``periodic_fuzzy_delay`` = ``60`` - (Integer) Range in seconds to randomly delay when starting the periodic task scheduler to reduce stampeding. (Disable by setting to 0). * - ``periodic_interval_max`` = ``60`` - (Integer) Max interval size between periodic tasks execution in seconds. * - ``periodic_workers_number`` = ``1`` - (Integer) Number of threads to run periodic tasks. * - ``plugins`` = ``vanilla, spark, cdh, ambari`` - (List) List of plugins to be loaded. Sahara preserves the order of the list when returning it. * - ``proxy_command`` = - (String) Proxy command used to connect to instances. If set, this command should open a netcat socket, that Sahara will use for SSH and HTTP connections. Use {host} and {port} to describe the destination. Other available keywords: {tenant_id}, {network_id}, {router_id}. * - ``remote`` = ``ssh`` - (String) A method for Sahara to execute commands on VMs. * - ``rootwrap_command`` = ``sudo sahara-rootwrap /etc/sahara/rootwrap.conf`` - (String) Rootwrap command to leverage. Use in conjunction with use_rootwrap=True * - ``swift_topology_file`` = ``etc/sahara/swift.topology`` - (String) File with Swift topology.It should contain mapping between Swift nodes and racks. * - ``use_barbican_key_manager`` = ``False`` - (Boolean) Enable the usage of the OpenStack Key Management service provided by barbican. * - ``use_floating_ips`` = ``True`` - (Boolean) If set to True, Sahara will use floating IPs to communicate with instances. To make sure that all instances have floating IPs assigned in Nova Network set "auto_assign_floating_ip=True" in nova.conf. If Neutron is used for networking, make sure that all Node Groups have "floating_ip_pool" parameter defined. * - ``use_identity_api_v3`` = ``True`` - (Boolean) Enables Sahara to use Keystone API v3. If that flag is disabled, per-job clusters will not be terminated automatically. * - ``use_namespaces`` = ``False`` - (Boolean) Use network namespaces for communication (only valid to use in conjunction with use_neutron=True). * - ``use_neutron`` = ``False`` - (Boolean) Use Neutron Networking (False indicates the use of Nova networking). * - ``use_rootwrap`` = ``False`` - (Boolean) Use rootwrap facility to allow non-root users to run the sahara-all server instance and access private network IPs (only valid to use in conjunction with use_namespaces=True) * - **[castellan]** - * - ``barbican_api_endpoint`` = ``None`` - (String) The endpoint to use for connecting to the barbican api controller. By default, castellan will use the URL from the service catalog. * - ``barbican_api_version`` = ``v1`` - (String) Version of the barbican API, for example: "v1" * - **[certificates]** - * - ``barbican_auth`` = ``barbican_acl_auth`` - (String) Name of the Barbican authentication method to use * - ``cert_manager_type`` = ``barbican`` - (String) Certificate Manager plugin.
