Package
Description
This package contains the implementation of the Protocol Buffers
protocols related to HDFS Router.
FedBalance is a tool for balancing data across federation clusters.
Includes router handlers fairness manager and policy implementations.
Report metrics for Router-based Federation.
The resolver package contains indepedent data resolvers used in HDFS
federation.
A federated location can be resolved to multiple subclusters.
The router package includes the core services for a HDFS federation router.
This package contains classes that facilitate asynchronous operations within the Hadoop
Distributed File System (HDFS) Federation router.
This package contains classes that facilitate asynchronous operations within the Hadoop
Distributed File System (HDFS) Federation router.
Includes router security manager and token store implementations.
Includes implementations of token secret managers.
The federation state store tracks persistent values that are shared between
multiple routers.
The state store uses modular data storage classes derived from
StateStoreDriver to handle querying, updating and deleting data records.
Implementations of state store data providers/drivers.
Contains implementations of the state store API interfaces.
Contains the abstract definitions of the API request and response objects for
the various state store APIs.
Protobuf implementations of FederationProtocolBase request/response objects
used by state store APIs.
Contains the abstract definitions of the state store data records.
The protobuf implementations of state store data records defined in the
org.apache.hadoop.hdfs.server.federation.store.records package.
Assorted utility classes and helpers for HDFS Federation.
It includes the tools to manage the Router-based federation.
