Harsh J updated YARN-116: ------------------------- Attachment: YARN-116.patch Cleaned up Xie's patch. Doesn't depend on YarnConfiguration in the refreshNodes signature, formatted the test-cases and removed unwanted checks. > RM is missing ability to add include/exclude files without a restart > -------------------------------------------------------------------- > > Key: YARN-116 > URL: https://issues.apache.org/jira/browse/YARN-116 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.0.0-alpha > Reporter: xieguiming > Attachments: HADOOP-835-0.patch, HADOOP-835-1.patch, > HADOOP-835.patch, YARN-116.patch > > > The "yarn.resourcemanager.nodes.include-path" default value is "", if we need > to add an include file, we must currently restart the RM. > I suggest that for adding an include or exclude file, there should be no need > to restart the RM. We may only execute the refresh command. The HDFS NameNode > already has this ability. > Fix is to the modify HostsFileReader class instances: > From: > {code} > public HostsFileReader(String inFile, > String exFile) > {code} > To: > {code} > public HostsFileReader(Configuration conf, > String NODES_INCLUDE_FILE_PATH,String > DEFAULT_NODES_INCLUDE_FILE_PATH, > String NODES_EXCLUDE_FILE_PATH,String > DEFAULT_NODES_EXCLUDE_FILE_PATH) > {code} > And thus, we can read the config file dynamically when a {{refreshNodes}} is > invoked and therefore have no need to restart the ResourceManager. -- This message is automatically generated by JIRA.
