--------------------------------------

             Summary: Add tez.task-specific configs into whitelist to modify at 
session level
                 Key: HIVE-28250
                 URL: https://issues.apache.org/jira/browse/HIVE-28250
             Project: Hive
          Issue Type: Improvement
            Reporter: Raghav Aggarwal
            Assignee: Raghav Aggarwal


When we try to set tez.task-specific configs at runtime, it doesn't allow it
{code:java}
: jdbc:hive2://localhost:10000> set tez.task-specific.launch.cmd-opts.list="Map 
1[0]";
Error: Error while processing statement: Cannot modify 
tez.task-specific.launch.cmd-opts.list at runtime. It is not in list of params 
that are allowed to be modified at runtime (state=42000,code=1) {code}
Putting this in whitelist will help to debug tez query easily otherwise, admin 
has to add the regex in 
_hive.security.authorization.sqlstd.confwhitelist.append_ config in Ambari UI 
and restart the HS2 process. 

Better to whitelist by default as we have already whitelisted, 
_*tez\\.task\\..**_ regex.
