<description>Index at which the RM Delegation Token ids will be split so
|
||||
that the delegation token znodes stored in the zookeeper RM state store
|
||||
will be stored as two different znodes (parent-child). The split is done
|
||||
from the end. For instance, with no split, a delegation token znode will
|
||||
be of the form RMDelegationToken_123456789. If the value of this config is
|
||||
1, the delegation token znode will be broken into two parts:
|
||||
RMDelegationToken_12345678 and 9 respectively with former being the parent
|
||||
node. This config can take values from 0 to 4. 0 means there will be no
|
||||
split. If the value is outside this range, it will be treated as 0 (i.e.
|
||||
no split). A value larger than 0 (up to 4) should be configured if you are
|
||||
running a large number of applications, with long-lived delegation tokens
|
||||
and state store operations (e.g. failover) are failing due to LenError in
|

Zookeeper.</description>
