Vinod Kumar Vavilapalli updated MAPREDUCE-2744: ----------------------------------------------- Priority: Minor (was: Major) > [MR-279] In unsercure mode, AM can fake resource requirements > -------------------------------------------------------------- > > Key: MAPREDUCE-2744 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2744 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: mrv2, security > Affects Versions: 0.23.0 > Reporter: Vinod Kumar Vavilapalli > Priority: Minor > Fix For: 0.23.1 > > > Without security, it is impossible to completely avoid AMs faking resources. > We can at the least make it as difficult as possible by using the same > container tokens and the RM-NM shared key mechanism over unauthenticated > RM-NM channel. > In the minimum, this will avoid accidental bugs in AMs in unsecure mode. -- This message is automatically generated by JIRA.
