-------------------------------------
Summary: Clients should be installed on all nodes by default
Key: AMBARI-11040
URL: https://issues.apache.org/jira/browse/AMBARI-11040
Project: Ambari
Issue Type: Bug
Reporter: Nick Dimiduk
I recently had the confusing experience of my MR job only running in local
mode. Listing HDFS worked fine and so did the HBase shell. I tried different
things to resolve (environment variables, classpaths, &c). Eventually I
realized that the mapreduce configs were not correct -- what was in stalled was
the default "empty" config. This was extra confusing because HDFS and HBase
were configured correctly. It seemed that the MR client had not been installed
on this host.
I think all clients should be installed on all hosts by default. Administrators
who want to lock down "server" nodes vs. "edge" nodes can do so via
customization. This is a pretty poor experience, a wide usability gap.
