MessageOrBuilder

Methods

getName()

public abstract String getName()

Output only. TaskGroup name. The system generates this field based on parent Job name. For example: "projects/123456/locations/us-west1/jobs/job01/taskGroups/group01".

string name = 1 [(.google.api.field_behavior) = OUTPUT_ONLY];

Returns
Type	Description
`String`	The name.

getNameBytes()

public abstract ByteString getNameBytes()

Output only. TaskGroup name. The system generates this field based on parent Job name. For example: "projects/123456/locations/us-west1/jobs/job01/taskGroups/group01".

string name = 1 [(.google.api.field_behavior) = OUTPUT_ONLY];

Returns
Type	Description
`ByteString`	The bytes for name.

getParallelism()

public abstract long getParallelism()

Max number of tasks that can run in parallel. Default to min(task_count, 1000). Field parallelism must be 1 if the scheduling_policy is IN_ORDER.

int64 parallelism = 5;

Returns
Type	Description
`long`	The parallelism.

getPermissiveSsh()

public abstract boolean getPermissiveSsh()

When true, Batch will configure SSH to allow passwordless login between VMs running the Batch tasks in the same TaskGroup.

bool permissive_ssh = 12;

Returns
Type	Description
`boolean`	The permissiveSsh.

getRequireHostsFile()

public abstract boolean getRequireHostsFile()

When true, Batch will populate a file with a list of all VMs assigned to the TaskGroup and set the BATCH_HOSTS_FILE environment variable to the path of that file. Defaults to false.

bool require_hosts_file = 11;

Returns
Type	Description
`boolean`	The requireHostsFile.

getTaskCount()

public abstract long getTaskCount()

Number of Tasks in the TaskGroup. Default is 1.

int64 task_count = 4;

Returns
Type	Description
`long`	The taskCount.

getTaskCountPerNode()

public abstract long getTaskCountPerNode()

Max number of tasks that can be run on a VM at the same time. If not specified, the system will decide a value based on available compute resources on a VM and task requirements.

int64 task_count_per_node = 10;

Returns
Type	Description
`long`	The taskCountPerNode.

getTaskEnvironments(int index)

public abstract Environment getTaskEnvironments(int index)

An array of environment variable mappings, which are passed to Tasks with matching indices. If task_environments is used then task_count should not be specified in the request (and will be ignored). Task count will be the length of task_environments.

Tasks get a BATCH_TASK_INDEX and BATCH_TASK_COUNT environment variable, in addition to any environment variables set in task_environments, specifying the number of Tasks in the Task's parent TaskGroup, and the specific Task's index in the TaskGroup (0 through BATCH_TASK_COUNT - 1).
