Hi, In the core Hadoop you can on your (desktop) client have multiple clusters available simply by having multiple directories with setting files (i.e. core-site.xml etc.) and select the one you want by changing the environment settings (i.e. HADOOP_CONF_DIR and such) around.
This doesn't work when I run under the Hortonworks 2.1.2 distribution. There I find that in all of the scripts placed in /usr/bin/ there is "mucking about" with the environment settings. Things from /etc/default are sourced and they override my settings. Now I can control part of it by directing the BIGTOP_DEFAULTS_DIR into a blank directory. But in /usr/bin/pig sourcing /etc/default/hadoop hardcoded into the script. Why is this done this way? P.S. Where is the git(?) repo located where this (apperently HW specific) scripting is maintained? -- Best regards / Met vriendelijke groeten, Niels Basjes
