> New API for libhdfs to get FileSystem object as a proxy user
> ------------------------------------------------------------
>
> Key: HADOOP-12953
> URL: https://issues.apache.org/jira/browse/HADOOP-12953
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.7.2
> Reporter: Uday Kale
> Assignee: Uday Kale
> Priority: Major
> Attachments: HADOOP-12953.001.patch, HADOOP-12953.002.patch,
> HADOOP-12953.003.patch, HADOOP-12953.004.patch

>
> Secure impersonation in HDFS needs users to create proxy users and work with
> those. In libhdfs, the hdfsBuilder accepts a userName but calls
> FileSytem.get() or FileSystem.newInstance() with the user name to connect as.
> But, both these interfaces use getBestUGI() to get the UGI for the given
> user. This is not necessarily true for all services whose end-users would not
> access HDFS directly, but go via the service to first get authenticated with
> LDAP, then the service owner can impersonate the end-user to eventually
> provide the underlying data.
> For such services that authenticate end-users via LDAP, the end users are not
> authenticated by Kerberos, so their authentication details wont be in the
> Kerberos ticket cache. HADOOP_PROXY_USER is not a thread-safe way to get this
> either.
> Hence the need for the new API for libhdfs to get the FileSystem object as a
> proxy user using the 'secure impersonation' recommendations. This approach is
> secure since HDFS authenticates the service owner and then validates the
> right for the service owner to impersonate the given user as allowed by
> hadoop.proxyusers.* parameters of HDFS config.
