Zhan Zhang commented on SPARK-5159:
-----------------------------------
This issue is definitely broken. But fixing it needs a complete design being
review first.
For example, to enable the impersonation (doAs) at runtime, how do we solve the
RDD sharing between different users?
We can propagate the user to the executor piggybacked by TaskDescription. But
what happen if two user operate on two RDDs which share the same parent, cache
created by another user. Currently, RDD scope is SparkContext without any user
information. It means even we do impersonation, it is meaningless per my
understanding.
> Thrift server does not respect hive.server2.enable.doAs=true

> I'm currently testing the spark sql thrift server on a kerberos secured
> cluster in YARN mode. Currently any user can access any table regardless of
> HDFS permissions as all data is read as the hive user. In HiveServer2 the
> property hive.server2.enable.doAs=true causes all access to be done as the
> submitting user. We should do the same.
