[jira] [Created] (HDFS-14850) Optimize
FileSystemAccessService#getFileSystemConfiguration
Lisheng Sun created HDFS-14850:
----------------------------------
Summary: Optimize FileSystemAccessService#getFileSystemConfiguration
Key: HDFS-14850
URL: https://issues.apache.org/jira/browse/HDFS-14850
Project: Hadoop HDFS
Issue Type: Improvement
Environment: *strong text*
Reporter: Lisheng Sun
Assignee: Lisheng Sun
{code:java}
@Override
public Configuration getFileSystemConfiguration() {
Configuration conf = new Configuration(true);
ConfigurationUtils.copy(serviceHadoopConf, conf);
conf.setBoolean(FILE_SYSTEM_SERVICE_CREATED, true);
// Force-clear server-side umask to make HttpFS match WebHDFS behavior
conf.set(FsPermission.UMASK_LABEL, "000");
return conf;
}
{code}
As above code,when call FileSystemAccessService#getFileSystemConfiguration,current code new Configuration every time.
It is not necessary and affects performance. I think it only need to new Configuration in FileSystemAccessService#init once and FileSystemAccessService#getFileSystemConfiguration get it.
