應廣東聯通項目的需求，近日bm增加了yarn隊列監控，監控最小粒度到隊列和用戶。
使用過程中，局方提出指標具體含義的問題，這些指標的含義官方沒有具體介紹，最好在hortonworks的介紹文檔中找到，分享如下。
yarn pending reserved allocate
Containers •
Allocated – Containers which have been created with requested resources. •
Pending – Containers, whose resources will become available and are pending creation. •
Reserved – Containers, whose resources are not yet available.
Examples 10 GB Cluster •
Request three 5GB containers • 2 allocated, 1 pending. •
Request three 4GB containers • 2 allocated, 1 reserved (2GB)
Applications • Submitted – Application requests made to YARN. • Running – Application with Masters which have been created and are running. • Pending – Application requests which are pending creation. • Completed – Applications which have completed running. They could have been successful, killed or failed. • Killed – Applications which have been terminated by user • Failed – Applications which have failed to run due to internal failures.
