Method Detail

getNMTokenCache

public static org.apache.hadoop.yarn.client.api.NMTokenCache getNMTokenCache()

Gets the Hadoop NMTokenCache. Access token cache via singleton method if exists, otherwise assumes that class is hadoop vanilla implementation with static methods where we can just use default constructor and further access for those static method would got via instance itself.

This is due to a fact that i.e. cloudera modified this class by removing static methods and made access to it via singleton pattern.

Returns:

the token cache
