All Implemented Interfaces:

org.apache.hadoop.conf.Configurable

public class HadoopCredentialConfiguration
extends EntriesCredentialConfiguration
implements org.apache.hadoop.conf.Configurable

CredentialConfiguration based on Hadoop Configuration objects. When reading configuration this class makes use of a list of key prefixes that are each applied to key suffixes to create a complete configuration key. There is a base prefix of 'google.cloud.' that is included by the builder for each HadoopCredentialConfiguration created. When constructing, other prefixes can be specified. Prefixes specified later can be used to override the values of previously set values. In this way a set of global credentials can be specified for most connectors with an override specified for any connectors that need different credentials.

getConf

public org.apache.hadoop.conf.Configuration getConf()

Translates the "Entries" configuration of the superclass into a Hadoop "Configuration" using getConfigurationInto() on a wrapper which passes through each key from the Entries to the corresponding Hadoop object.

Specified by:

getConf in interface org.apache.hadoop.conf.Configurable

setConf

@Deprecated
public void setConf(org.apache.hadoop.conf.Configuration entries)

Deprecated. never used

Load configuration values from the provided Configuration source. For any key that does not have a corresponding value in the Configuration, no changes will be made to the state of this object.
