    [ https://issues.apache.org/jira/browse/MAPREDUCE-4119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13249224#comment-13249224

xieguiming commented on MAPREDUCE-4119:

this is the job history server the the intermediateDoneDirPath dir logic.

and the intermediateDoneDirPath value from the local conf. and the local conf maybe different
with the real job yarn.app.mapreduce.am.staging-dir.


  public static String getConfiguredHistoryIntermediateDoneDirPrefix(
      Configuration conf) {
    String doneDirPrefix = conf
    if (doneDirPrefix == null) {
      doneDirPrefix = conf.get(MRJobConfig.MR_AM_STAGING_DIR,
          + "/history/done_intermediate";
    return doneDirPrefix;

> jobclient can set the yarn.app.mapreduce.am.staging-dir value , but jobhistoryserver
only read the yarn.app.mapreduce.am.staging-dir  value from conf.
> so, if client set different yarn.app.mapreduce.am.staging-dir value, and the jobhistoryserver
can not scan the directory.
