<description>Index at which last section of application id (with each section
|
||||
separated by _ in application id) will be split so that application znode
|
||||
stored in zookeeper RM state store will be stored as two different znodes
|
||||
(parent-child). Split is done from the end.
|
||||
For instance, with no split, appid znode will be of the form
|
||||
application_1352994193343_0001. If the value of this config is 1, the
|
||||
appid znode will be broken into two parts application_1352994193343_000
|
||||
and 1 respectively with former being the parent node.
|
||||
application_1352994193343_0002 will then be stored as 2 under the parent
|
||||
node application_1352994193343_000. This config can take values from 0 to 4.
|
||||
0 means there will be no split. If configuration value is outside this
|
||||
range, it will be treated as config value of 0(i.e. no split). A value
|
||||
larger than 0 (up to 4) should be configured if you are storing a large number
|
||||
of apps in ZK based RM state store and state store operations are failing due to
|
||||
LenError in Zookeeper.</description>
