Daryn Sharp commented on HDFS-3113:
-----------------------------------
Just to make sure I understand: WebHDFS client -> HttpFS -> SomeFS. Is HttpFS
acting like a pure proxy and relaying the real token for SomeFS back to the
client? If so, what's the purpose of the secret manager in httpfs?
Regarding token decoding, this:
{code}
ByteArrayInputStream buf = new ByteArrayInputStream(token.getIdentifier());
DataInputStream dis = new DataInputStream(buf);
DelegationTokenIdentifier id = new DelegationTokenIdentifier();
id.readFields(dis);
dis.close();{code}
can be replaced with {{DelegationTokenIdentifier id = token.decodeIdentifier()}}
BTW, have you tested this with oozie to ensure proxy tokens work correctly?
