Methods and systems for automated scheduler-controlled pre-job deployment node health testing in a computing cluster

A computer-program product comprising a non-transitory machine-readable storage medium storing computer instructions that, when executed by one or more processors, perform operations comprising:

• identifying a target set of computing nodes within the cluster of computing nodes that are scheduled to execute a job at a future start time based on identifying, by a computing task scheduler, a request to execute the job within a cluster of computing nodes;
• submitting prior to the future start time, by the computing task scheduler, a set of initial health tests of the node health assessment to the target set of computing nodes for execution based on the identification of the target set of computing nodes;
• identifying at least one pair of computing nodes that failed the set of initial tests of the node health assessment based on the assessment results obtained from an execution of the set of initial health tests by the target set of computing nodes;
• isolating the at least one pair of computing nodes from a remainder of the computing nodes of the target set of computing nodes that did not fail the set of initial tests;
• submitting one or more additional health tests to each computing node of the at least one pair of computing nodes;
• identifying a given computing node of the least one pair of computing nodes as being an unhealthy computing node based on assessment results obtained from an execution of the one or more additional health tests;
• and
• adapting an operating state of the unhealthy computing node from a state of available for executing the job to a state of unavailable for executing the job based on identifying the given computing node as the unhealthy computing node.

A computer-implemented method comprising:

• identifying a target set of computing nodes within the cluster of computing nodes that are scheduled to execute a job at a future start time based on identifying, by a task scheduler, a request to execute the job within a cluster of computing nodes;
• submitting by the task scheduler, during an execution of a prolog script, a set of initial health tests to the target set of computing nodes for execution based on the identification of the target set of computing nodes;
• identifying at least one pair of computing nodes that failed the set of initial tests based on the assessment results obtained from an execution of the set of initial health tests by the target set of computing nodes;
• isolating the at least one pair of computing nodes from a remainder of the computing nodes of the target set of computing nodes that did not fail the set of initial health tests;
• submitting an additional health test to each computing node of the at least one pair of computing nodes;
• identifying a given computing node of the least one pair of computing nodes as being an unhealthy computing node based on assessment results obtained from an execution of the additional health test;
• and
• adapting an operating state of the unhealthy computing node from a state of available for executing the job to a state of unavailable for executing the job based on identifying the given computing node as the unhealthy computing node.
