convertFromYarn

public static <T extends org.apache.hadoop.security.token.TokenIdentifier> org.apache.hadoop.security.token.Token<T> convertFromYarn(Token protoToken,
                                                                                                                                     InetSocketAddress serviceAddr)

Convert a protobuf token into a rpc token and set its service. Supposed to be used for tokens other than RMDelegationToken. For RMDelegationToken, use convertFromYarn(org.apache.hadoop.yarn.api.records.Token, org.apache.hadoop.io.Text) instead.

Parameters:

protoToken - the yarn token

serviceAddr - the connect address for the service

Returns:

rpc token

convertFromYarn

public static <T extends org.apache.hadoop.security.token.TokenIdentifier> org.apache.hadoop.security.token.Token<T> convertFromYarn(Token protoToken,
                                                                                                                                     Text service)

Convert a protobuf token into a rpc token and set its service.

Parameters:

protoToken - the yarn token

service - the service for the token
