(3) task white list white tasks are obtained：Task white list list is obtained by inquiring about database, after being easy to
The task validity checking in face, the task in white list skip over；
(4) the task task set being currently running are obtained：Set of tasks is obtained by hadoop api；
(5) judge whether task set are empty, be then to perform step (6), otherwise perform step (8)；
(6) a task task is removed from task set：A task is taken out from task set；
(7) single task legitimacy is checked：The indices of inspection task, judge whether task is illegal, jump to step
Suddenly (5)；
(8) terminate.
The present invention is quasi real time protected the safety of hadoop systems, supervised in real time automatically by the automatic Predicated execution of whole process
The occupation condition of each task of hadoop cluster is controlled, discovery task, which takes resource, will excessively close task automatically.
A kind of hadoop Mission Monitors system is additionally provided, the system includes：
Initialization module, it is configured to perform the operation of initialization；
User's white list module is obtained, it is configured to obtain the name on account list having permission by inquiring about database, just
Task user name validity checking later；
Acquisition task white list module, its configure come by inquire about database obtain task white list list, be easy to behind
Task validity checking, the task in white list skips over；
The task module being currently running is obtained, it, which is configured, to obtain set of tasks by hadoop api；
Judge module, it is configured to judge whether task set are empty, is then to perform to remove module, is otherwise terminated；
Module is removed, it, which is configured, to remove a task task from task set：One is taken out from task set to appoint
Business；
Module is checked, it is configured to check single task legitimacy：Whether the indices of inspection task, judge task
Illegally, judge module is jumped to.
Brief description of the drawings
Fig. 1 show the flow chart of the hadoop Mission Monitor methods according to the present invention.
Fig. 2 show the flow chart of the step of hadoop Mission Monitor methods according to the present invention (7).
Embodiment

Step (7.8)；
(7.3) judge whether the task is white list task, if it is abandons checking, perform step (7.9), otherwise hold
Row step (7.4)；
(7.4) judge that the map numbers of inspection task whether beyond regulation, if it is perform step (7.8), otherwise perform step
Suddenly (7.5)；
(7.5) judge that the reduce numbers of inspection task whether beyond regulation, if it is perform step (7.8), otherwise held
Row step (7.6)；
(7.6) judge that the output quantity of inspection task whether beyond regulation, if it is performs step (7.8), otherwise performed
Step (7.7)；
(7.7) judge whether the run time of inspection task exceeds defined length, if it is perform step (7.8),
Otherwise step (7.9) is performed；
(7.8) task is killed, mail is sent to user：Judge that the task is illegal, kill the task and give submission the task
User send circular mail；
(7.9) individual task inspection terminates：Individual task inspection terminates, the partial information data-in storehouse of task.
In addition, in the step (7.4), map numbers are 20000.
In addition, in the step (7.5), reduce numbers are 1000.
In addition, in the step (7.6), the output quantity of task is 5T.
