Hitesh Shah commented on TEZ-1710:
----------------------------------
Comments:
- question is which value overrides the other? As per offline discussions, it
seems that the rightmost command line option likely wins. In this, we should
put "admin" settings at the rightmost. If we are referring to these as cluster
defaults which can be overridden by the user then a diff naming convention
should used.
If we designate this to be cluster defaults, I think we should change our
current default values of command opts to cluster defaults and keep the config
default for user specified opts to be "".
For addDefaultsToTaskLaunchCmdOpts(), we have 3 ways to specific opts:
- programmatic on vertex api
- user configured opts
- cluster default opts
What should be the order of priority ( assuming cluster default is always
lowest ) ? Also, do we only pick one of the 2 from programmatic vs user config?
Any reason for the change in YARNRunner? i.e.
"dagAMConf.set(TezConfiguration.TEZ_AM_LAUNCH_CMD_OPTS, javaOpts.toString());"
?
