Subject [jira] [Created] (HADOOP-8803) Make Hadoop running more secure public cloud envrionment
Date Thu, 13 Sep 2012 17:24:08 GMT
Xianqing Yu created HADOOP-8803:
-----------------------------------

             Summary: Make Hadoop running more secure public cloud envrionment
                 Key: HADOOP-8803
                 URL: https://issues.apache.org/jira/browse/HADOOP-8803
             Project: Hadoop Common
          Issue Type: New Feature
          Components: fs, ipc, security
    Affects Versions: 0.20.204.0
            Reporter: Xianqing Yu


I have two major goals in the project.

One is bring fine-grain access control to Hadoop. Based on 0.20.204, Hadoop 
access control is based on user or block granularity, e.g. HDFS Delegation 
Token only check if the file can be accessed by certain user or not, Block 
Token only proof which block or blocks can be accessed. I would like to make 
Hadoop can do byte-granularity access control, each access party, user or 
task process can only access the bytes she or he least needed.

Second one is that make Hadoop work more secure in Cloud environment, 
especially in public Cloud environment. So the communication between 
hadoop's node should be protected. And if some nodes of hadoop is 
compromised, the damage should be minimized (e.g. known wildly shared-key 
problem of Block Access Token problem).
