---------------------------------------
Summary: IGFS: Create user name converter for Hadoop secondary
file system.
Key: IGNITE-3202
URL: https://issues.apache.org/jira/browse/IGNITE-3202
Project: Ignite
Issue Type: Task
Components: hadoop, IGFS
Affects Versions: 1.5.0.final, 1.6
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Priority: Critical
Fix For: 1.7
*Problem*
When user access secondary file system, we propagate it form client machine to
Ignite server and then try to perform the request on this user using either
"doAs" or proxies in case of Kerberos.
The problem is that user name is not always match what we need. For example,
user name is "ivanov", but the request should be performed using proxied user
"ivanov@[REALM_NAME]".
*Solution*
We need to introduce special converter interface which will intercept user
names and convert them to correct form if needed. This interceptor should be
places inside file system factory.
