[jira] [Updated] (HDFS-2301) Start/stop appropriate namenode internal services during transition to active and standby
[ https://issues.apache.org/jira/browse/HDFS-2301?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Suresh Srinivas updated HDFS-2301: -- Attachment: HDFS-2301.txt h3. Current behavior: Namenode starts the following services: # FSNamesystem secret manager # FSNamesystem activation performs: #* NNResourceChecker, activate block manager, starts lease manager thread, resource monitor threads and register mbeans and initializes metrics. # Starts http server, rpc server, trash emptier, service plugins Backup node starts all the services above except: # secret manager # Sets lease period to MAX_VALUE, effectively not use lease manager. h3. Proposed behavior: Following services are started as common to both active and standby namenode states: # Starts common FSNamesystem common services to both active and standby #* TODO # Starts http server, rpc server, service plugins Following services are started when moving to active state and stopped when exiting active state: # Start/stops FSNamesystem active services: #* Which starts/stop FSNamesystem secrtet manager and lease manager. Currently standby state services are marked as TODO. This is where reading editlogs from active will be handled. BackupNode with this patch will no longer start lease manager thread. h3. Code changes # HAState no longer knows about NameNode. Instead NameNode exposes HAContext # Reorganized and cleaned up the code for starting and stopping services. > Start/stop appropriate namenode internal services during transition to active > and standby > - > > Key: HDFS-2301 > URL: https://issues.apache.org/jira/browse/HDFS-2301 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: name-node >Affects Versions: HA branch (HDFS-1623) >Reporter: Suresh Srinivas >Assignee: Suresh Srinivas > Fix For: HA branch (HDFS-1623) > > Attachments: HDFS-2301.txt > > > These changes are related to HDFS-1974 which introduced active and standby > states.
