-----------------------------------------
Summary: Implement getHomeDirectory() method in
NativeAzureFileSystem
Key: HADOOP-14150
URL: https://issues.apache.org/jira/browse/HADOOP-14150
Project: Hadoop Common
Issue Type: Improvement
Components: fs/azure
Affects Versions: 2.8.0
Reporter: Santhosh G Nayak
Assignee: Santhosh G Nayak
{{org.apache.hadoop.fs.azure.NativeAzureFileSystem}} does not override
{{FileSystem#getHomeDirectory()}} method.
So, whenever {{NativeAzureFileSystem#getHomeDirectory()}} gets called
{{getHomeDirectory()}} from {{FileSystem}} will be invoked, which has code like
below,
{code}
public Path getHomeDirectory() {
return this.makeQualified(
new Path(USER_HOME_PREFIX + "/" + System.getProperty("user.name")));
}
{code}
In secure environment, it returns home directory of
{{System.getProperty("user.name")}} instead of Kerberos principal/UGI.
So, the proposal is to override the {{getHomeDirectory()}} method in
{{NativeAzureFileSystem}} and have it return the home directory for the
Kerberos principal/ugi.
