Hi,
I am using CDH4.01 from a tarball and so far everything works kind of ok
(albeit quite different from CDH3). It seems though that I fail to get an
embedded job history server running when using YARN. On the other hand,
there is no $HADOOP_HOME/sbin/start-historyserver.sh or the like. I can
start the history server using mr-jobhistory-deamon.sh with appropriate
params.
Please use HADOOP_PREFIX instead of HADOOP_HOME. The latter's been deprecated.
As you've found out, using the following is the correct way for
starting the MR2 Job History Server when starting via a tarball:
$ sbin/start-historyserver.sh start historyserver
In other words: Is there a way to have an embedded job history server (small
setup) when using YARN?
By "embedded" do you mean a non-separate daemon for MR jobs? Or do you
mean start-yarn.sh itself starting the
YARN and MR2 (which uses YARN) are two separate set of components, and
hence start-yarn.sh doesn't also start the MR-specific job history
server. The JHS doesn't apply/work for any other apps of YARN other
than MR2 right now, so its not unified.
Thanks,
Henning
