----------------------------------
Summary: Add exclude/include file , need restart NN or RM.
Key: HADOOP-8351
URL: https://issues.apache.org/jira/browse/HADOOP-8351
Project: Hadoop Common
Issue Type: Bug
Components: util
Environment: suse
Reporter: xieguiming
"yarn.resourcemanager.nodes.include-path" default value is "", if we need add
one include file. and we must restart the RM.
I suggest that adding one include or exclude file, no need restart the RM. only
execute the refresh command.
NN is the same.
Modify the HostsFileReader class:
public HostsFileReader(String inFile,
String exFile)
to
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)
and thus, we can read the config file dynamic. and no need to restart the NM/NN.
