Wei-Chiu Chuang updated HDFS-10187: ----------------------------------- Labels: commandline supportability (was: supportability) > Add a "list" refresh handler to list all registered refresh > identifiers/handlers > -------------------------------------------------------------------------------- > > Key: HDFS-10187 > URL: https://issues.apache.org/jira/browse/HDFS-10187 > Project: Hadoop HDFS > Issue Type: New Feature > Affects Versions: 2.7.2 > Reporter: Wei-Chiu Chuang > Assignee: Wei-Chiu Chuang > Labels: commandline, supportability > Attachments: HDFS-10187.001.patch > > > HADOOP-10376 added a new feature to register handlers for refreshing daemon > configurations, because name node properties can be reconfigured without > restarting the daemon. This can be a very useful generic interface, but so > far no real handlers have been registered using this interface. I added a new > 'list' handler to list all registered handlers. My plan is to add more > handlers in the future using this interface. > Another minor fix is return a more explicit error message to the client if a > handler is not registered. (It is currently logged at namenode side, but > client side only gets a "Failed to get response." message without knowing why) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
