Number of seconds after an application finishes before the nodemanager's
|
||||||
|
DeletionService will delete the application's localized file directory
|
||||||
|
and log directory.
|
||||||
|
|
||||||
|
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).
