Simbarashe Dzinamarira updated HDFS-16943:
------------------------------------------
Description:
RBF supports two types of StateStoreDrivers
# StateStoreFileImpl
# StateStoreZooKeeperImpl
I propose implementing a third driver that is backed by MySQL.
* StateStoreZooKeeperImpl requires an additional Zookeeper cluster.
* StateStoreFileImpl can use one of the namenodes in the HDFS cluster, but
that namenode becomes a single point of failure, introducing coupling between
the federated clusters.
HADOOP-18535 implemented a MySQL token store. When tokens are stored in MySQL,
using MySQL for the StateStore as well reduces the number of external
dependencies for routers.
