Masatake Iwasaki commented on MAPREDUCE-6525:
---------------------------------------------
{{MiniMRYarnClusterAdapter#restart}} creates new MiniMRYarnCluster with
configuration of existing MiniMRYarnCluster. MiniMRYarnCluster tries to copy
the value of {{JHAdminConfig.MR_HISTORY_ADDRESS}} in the configuration of
JobHistoryServer (updated by using {{Configuration#updateConnectAddr}}) in
startup.
{code}
//need to do this because historyServer.init creates a new Configuration
getConfig().set(JHAdminConfig.MR_HISTORY_ADDRESS,
historyServer.getConfig().get(JHAdminConfig.MR_HISTORY_ADDRESS));
MRWebAppUtil.setJHSWebappURLWithoutScheme(getConfig(),
MRWebAppUtil.getJHSWebappURLWithoutScheme(historyServer.getConfig()));
{code}
According to the log of minicluster, the updated value seems not yet to be
visible at above point.
before restart:
