To diagnose Yarn application problems, set this property's value large enough (for example, to 600 = 10 minutes) to permit examination of these directories. After changing the property's value, you must restart the nodemanager in order for it to have an effect. The roots of Yarn applications' work directories is configurable with the yarn.nodemanager.local-dirs property (see below), and the roots of the Yarn applications' log directories is configurable with the yarn.nodemanager.log-dirs property (see also below). yarn.nodemanager.delete.debug-delay-sec 600
