Hi, Any change in the Hadoop/HDFS/HBase environment that impacts Trafodion's understanding of the underlying environment, especially considering that Trafodion keeps a local copy of hbase-site.xml in /usr/lib/trafodion.
#Copy hbase-site.xml file sudo cp /etc/hbase/conf/hbase-site.xml $HOME sudo chown $(whoami).$(whoami) $HOME/hbase-site.xml sudo chmod 777 $HOME/hbase-site.xml sudo cp $HOME/hbase-site.xml $TRAF_WORKDIR sudo chown trafodion.trafodion $TRAF_WORKDIR/hbase-site.xml Overall, I am wondering whether it's necessary to rerun the Trafodion Installer for any other reason than a new software version? I don't understand whether any information in hbase-site.xml impacts runtime but the code above makes me wonder about the relationship between HBase configuration changes and impact on Trafodion. Related, I'm trying to understand how an upgrade from one release to another happens of there are changes to the Trafodion Installer. From what I understand, the upgrade must be done from the same node as the initial install was made because /etc/trafodion and /usr/bin/trafodion contains more information than on the other nodes? Other than that, you can download a new binary file for both the installer and the server code, run the installer, and upgrade will occur. If you used a --config_file, then you reuse it. Can you change it to combine a configuration change; for example, add new nodes?
