Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are only used for convenience of expression and should not be construed as a limitation to the embodiments of the present invention, and no description is given in the following embodiments.
Based on the above object, a first aspect of the embodiments of the present invention provides an embodiment of a method for optimizing performance of a big data cluster. Fig. 1 is a schematic diagram illustrating an embodiment of a method for optimizing large data cluster performance according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, creating a plurality of CPU virtual cores based on the number of the CPU physical cores, and locking the CPU virtual cores with a preset number as reserved CPUs;
s2, judging whether the CPU core number resources occupied by the current process number exceed a threshold value;
s3, responding to the CPU core number resources occupied by the current process number exceeding a threshold value, and judging whether processes densely scheduled by the CPU exist or not; and
and S4, responding to the process of the CPU intensive scheduling, unlocking the reserved CPU and executing the process of the CPU intensive scheduling by using the reserved CPU.
A plurality of CPU virtual cores are created based on the number of CPU physical cores, and a predetermined number of CPU virtual cores are locked as reserved CPUs. The CPU virtual cores are arranged in the big data cluster, for example, the number of the CPU virtual cores can be set to be 2 times of the number of the CPU physical cores, and the CPU physical cores can be managed and scheduled by managing the CPU virtual cores. A predetermined number of CPU virtual cores may be locked as reserved CPUs, and the predetermined number may be set according to specific situations, for example, 12% of the virtual cores may be set as reserved CPUs.
In some embodiments, said locking a predetermined number of said CPU virtual cores as reserved CPUs comprises: and sending a signal that the reserved CPU resource is occupied to a resource manager. For example, the virtual core selected to the reserved CPU sends a signal that the resource is occupied to the ResourceManager through the nodemanager (node manager) of each node, and thus, these reserved CPUs indicate the occupied status.
And judging whether the CPU core number resources occupied by the current process number exceed a threshold value. And responding to the CPU core number resources occupied by the current process number exceeding a threshold value, and judging whether processes densely scheduled by the CPU exist or not. Monitoring can be set in a resource manager of a big data platform, and processes and corresponding container requests initiated from each node manager of a cluster to an applicationmaster are monitored. The available resource report can be obtained through a resource manager, and when the number of processes occupies more than 70% of the CPU resources in the resource container, the cluster is judged to be in a multi-process concurrence state and a CPU use frequency state. At this time, whether a process of intensive CPU scheduling exists is detected.
In some embodiments, the determining whether there is a CPU-intensive scheduling process comprises: and sequentially judging whether dense response identification exists in each process. When a resource request is sent to the Applicationmaster, an identifier can be set for the process, namely the process is identified as a process with intensive CPU scheduling, and when the ResourceManager and the Applicationmaster schedule resources, the reserved CPU is released and packed into a container on the basis of the number of CPU cores allocated by the resource scheduler so as to support the calculation power of the process.
In some embodiments, the determining whether there is a CPU-intensive scheduling process comprises: and monitoring a resource container corresponding to the process, and judging whether the task number of the memory release time in the resource container, which is greater than the preset time, exceeds a second threshold value. Monitoring the container under the concurrent process task, and setting the normal memory release time of the container as m. If the number of tasks with the memory release time exceeding m under the container is more than 30%, the process can be determined to be a process intensively scheduled by the CPU.
And responding to the process with the CPU intensive scheduling, unlocking the reserved CPU and executing the process with the CPU intensive scheduling by using the reserved CPU. The reserved cpu release can be packed as container to join this process.
