[jira] [Updated] (HDFS-10687) Federation Membership State Store internal APIs
[ https://issues.apache.org/jira/browse/HDFS-10687?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Jason Kace updated HDFS-10687: -- Attachment: HDFS-10467-HDFS-10687-001.patch Attaching first patch version for review. This patch contains some overlap code (common dependencies) with HDFS-10630 (Federation State Store). The code compiles as is, but is not functional until HDFS-10630 is committed. The Federation membership state API functions are defined in org.apache.hadoop.hdfs.server.federation.store.FederationMembershipStateStore.java and are implemented in org.apache.hadoop.hdfs.server.federation.store.impl.FederationMembershipStateStoreImpl.java. The primary function of the membership state API is to persist the data required to identify the most active, or recently active, NN for each nameservice. This is a key feature for HDFS federation. Individual routers monitor 1-N namenodes and heartbeat the namenode status into the state store. The NN heartbeat code is available for review in HDFS-10629. This patch contains the APIs to query, update and cache the reported state of all NNs in the cluster. The additional files pertain to request/response API objects and the protobuf backing implementation of them.
