[jira] [Updated] (HADOOP-16977) in javaApi, UGI params should be
overidden through FileSystem conf
[ https://issues.apache.org/jira/browse/HADOOP-16977?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hongbing Wang updated HADOOP-16977:
-----------------------------------
Description:
org.apache.hadoop.security.UserGroupInformation#ensureInitialized,will always get the configure from the configuration files. Like below：
{code:java}
private static void ensureInitialized() {
if (conf == null) {
synchronized(UserGroupInformation.class) {
if (conf == null) { // someone might have beat us
initialize(new Configuration(), false);
}
}
}
}{code}
So that, if FileSystem is created through FileSystem#get or FileSystem#newInstance with conf*, the conf values different from the configuration files will not take effect in UserGroupInformation.* E.g:
{code:java}
Configuration conf = new Configuration();
conf.set("k1","v1");
conf.set("k2","v2");
FileSystem fs = FileSystem.get(uri, conf);{code}
"k1" or "k2" will not work in UserGroupInformation.
