I have to change the namenode heapsize (i.e. HADOOP_NAMENODE_OPTS) on a system where the web GUI is not available. I can access the API via curl, and I can use settings.sh. I looked at all settings using settings.sh in "hdfs-site", but there was nothing that looked remotely like what I need. So I believe I need to talk to the API directly. Any hints, especially pointers to documentation, are greatly appreciated.
