Method Detail

getNumRegisteredProviders

public int getNumRegisteredProviders()

Returns the number of providers that have been registered.

getInstance

public static SaslClientAuthenticationProviders getInstance(org.apache.hadoop.conf.Configuration conf)

Returns a singleton instance of SaslClientAuthenticationProviders.

reset

public static void reset()

Removes the cached singleton instance of SaslClientAuthenticationProviders.

getSimpleProvider

public Pair<SaslClientAuthenticationProvider,org.apache.hadoop.security.token.Token<? extends org.apache.hadoop.security.token.TokenIdentifier>> getSimpleProvider()

Returns the provider and token pair for SIMPLE authentication. This method is a "hack" while SIMPLE authentication for HBase does not flow through the SASL codepath.

selectProvider

public Pair<SaslClientAuthenticationProvider,org.apache.hadoop.security.token.Token<? extends org.apache.hadoop.security.token.TokenIdentifier>> selectProvider(String clusterId,
                                                                                                                                                                User clientUser)

Chooses the best authentication provider and corresponding token given the HBase cluster identifier and the user.
