    Ports

    Port type Number Required Description Metadata

    Input

    0

    Input tokens with identifications of interrupted graphs.

    Any

    Output

    0

    Final graph execution status.

    Metadata

    KillGraph does not propagate metadata from left to right or from right to left.

    This component has metadata templates. The templates are described in Details. General details on metadata templates are available in metadata templates.

    KillGraph attributes

    Attribute Req Description Possible values

    Basic

    Run ID

    no

    Specifies the run ID of an interrupted graph. Has higher priority than the Execution group attribute. This attribute can be overridden in input mapping.

    long

    Execution group

    no

    All graphs belonging to the specified execution group are interrupted. The Run ID attribute has higher priority. This attribute can be overridden in input mapping.

    string

    Kill daemon children

    no

    Specifies whether even daemon children are interrupted. Non-daemon children are aborted in any case. This attribute can be overridden in input mapping.

    false (default) | true

    Input mapping

    no

    Input mapping defines how to extract Run ID or Execution group to be interrupted from incoming token. See Input mapping.

    CTL transformation

    Output mapping

    no

    Output mapping defines how to populate the output token by final graph status of interrupted graph. See Output mapping.

    CTL transformation

    Details

    The KillGraph component aborts graphs specified by Run ID or by Execution group (all graphs belonging to the Execution group are aborted). Final execution status of interrupted graphs is passed to the output port or just printed out to a log. Moreover, you can choose if even daemon children of interrupted graphs are aborted (non-daemon children are interrupted in any case) - see the Execute graph as daemon attribute of ExecuteGraph.

    The component reads an input token, extracts Run ID or Execution group from incoming data (see the Input mapping attribute), interrupts the requested graphs and writes final status of the interrupted graph to the output port (see the Output mapping attribute).

    In case the input port is not attached, just the graphs specified in the Run ID attribute or in Execution group attribute are interrupted.

    Input mapping

    Input mapping is regular CTL transformation which is executed for each input token to extract Run ID or Execution group to be interrupted. Output record has following structure:

    Field Name Type Description

    runId

    long

    Overrides component attribute Run ID

    executionGroup

    string

    Overrides component attribute Execution group

    killDaemonChildren

    boolean

    Overrides component attribute Kill daemon children

    Output mapping

    Output mapping is regular CTL transformation which is executed for interrupted graph to populate the output token. Available input data has following structure:

    Field Name Type Description

    runId

    long

    run ID of interrupted graph

    originalJobURL

    string

    path to interrupted graph

    version

    string

    version of interrupted graph

    submitTime

    long

    time when the graph execution was requested. The graph can be enqueued and started later, see startTime below. See Job queue for more details about job queue.

    startTime

    date

    time of graph startup. If the graph was enqueued, this is the time when the graph was taken from the queue and started. See Job queue for more details about job queue.

    endTime

    date

    time of graph finish

    duration

    long

    graph run execution time in milliseconds (endTime - startTime)

    status

    string

    final graph execution status (FINISHED_OK | ERROR | ABORTED | TIMEOUT)

    errException

    string

    cause exception for failed graphs

    errMessage

    string

    error message for failed graphs

    errComponent

    string

    component ID which caused the graph to fail

    errComponentType

    string

    type of component which caused the graph to fail
