摘要： The present invention extends to methods, systems, and computer program products for propagating unhandled exceptions in distributed execution environments, such as clusters. A job (e.g., a query) can include a series of computation steps that are executed on multiple compute nodes each processing parts of a distributed data set. Unhandled exceptions can be caught while computations are running on data partitions of different compute nodes. Unhandled exception objects can be stored in a serialized format in a compute node's local storage (or an alternate central location) along with auxiliary details such as the data partition being processed at the time. Stored serialized exception objects for a job can be harvested and aggregated in a single container object. The single container object can be passed back to the client.

摘要： A scheduler receives a job graph which includes a graph of computational vertices that are designed to be executed on multiple distributed computer systems. The scheduler queries a graph manager to determine which computational vertices of the job graph are ready for execution in a local execution environment. The scheduler queries a cluster manager to determine the organizational topology of the distributed computer systems to simulate the determined topology in the local execution environment. The scheduler queries a data manager to determine data storage locations for each of the computational vertices indicated as being ready for execution in the local execution environment. The scheduler also indicates to a vertex spawner that an instance of each computational vertex is to be spawned in the local execution environment based on the organizational topology and indicated data storage locations, and indicates to the local execution environment that the spawned vertices are to be executed.
