Philip Zeyliger resolved BIGTOP-1054.
-------------------------------------
Resolution: Cannot Reproduce
My mistake: the MR1 port stuff isn't in any Bigtop releases, so this isn't
applicable.
> HADOOP_MAPRED_HOME is cumbersome
> --------------------------------
>
> Key: BIGTOP-1054
> URL: https://issues.apache.org/jira/browse/BIGTOP-1054
> Project: Bigtop
> Issue Type: Bug
> Reporter: Philip Zeyliger
>
> Currently, to run "yarn jar myjob.jar" you have to set the following in
> hadoop-env.sh.
> {code}
> HADOOP_MAPRED_HOME=/usr/lib/hadoop-mapreduce
> {code}
> This is a bit annoying if you're dealing with multiple Hadoop client
> configurations. I'd like to propose the following for consideration:
> # If the user is using "yarn" (the binary) we default HADOOP_MAPRED_HOME to
> the implementation of MR2 that we shipped with. Since the {{yarn}} binary
> knows its name, and knows the relative path to hadoop-mapreduce, this would
> be an easy default to implement.
> # We have a softer way to trigger "prefer yarn" rather than specifying the
> directory. E.g., HADOOP_MAPRED_PREFER_MR2 This makes it easier to switch
> betwen the two without remember the details of where the directory is.
> Thoughts!
> Thanks!
