Richard commented on SQOOP-1528:
--------------------------------
It is a small feature depends on delegation token task.
The server get the client's credential from http request, and run job with
proxy mode (the sqoop user delegates the real client user).
{code:title=MapreduceSubmissionEngine.java}
UserGroupInformation user = HttpUserGroupInformation.get();
// If we're in local mode than wait on completion. Local job runner do not
// seems to be exposing API to get previously submitted job which makes
// other methods of the submission engine quite useless.
if (isLocal()) {
user.doAs(
new PrivilegedExceptionAction<Void>() {
@Override
public Void run() throws Exception {
job.waitForCompletion(true);
return null;
}
});
} else {
user.doAs(
new PrivilegedExceptionAction<Void>() {
@Override
public Void run() throws Exception {
job.submit();
return null;
}
});
}
{code}
