Daryn Sharp created HDFS-4560:
---------------------------------
Summary: Webhdfs cannot use tokens obtained by another user
Key: HDFS-4560
URL: https://issues.apache.org/jira/browse/HDFS-4560
Project: Hadoop HDFS
Issue Type: Bug
Components: webhdfs
Affects Versions: 3.0.0, 0.23.7, 2.0.4-beta
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Webhdfs passes {{UserParam}} even when a token is being used. The NN will
construct the UGI from the token and error if the {{UserParam}} does not match
the token's. This causes problems when a token for user A is used with user
B's context. This is in contrast to hdfs which will honor the token's ugi no
matter the client's current context. The passing of a token or user params
should be mutually exclusive.
