Same issue here. As suggested, I am working it around, by directly specifying the active namenode's ip in DFS storage plug-in.
However, when I use hive storage plugin I still get: Error: SYSTEM ERROR: UnknownHostException: denominator even though I configured fs.default.name to also point to the active namenode's ip: { > "type": "hive", > "enabled": true, > "configProps": { ... "fs.default.name": "hdfs://ACTIVE_NAMENODES_IP:8020", } > } So I guess that behind the scenes there's still some fetching of the configuration from core-site.xml/hdfs-site.xml. Any idea how to work around this? Otherwise, it seems impossible to use hive plugin on a HA configured cluster. Maybe someone could elaborate on the suggestion of passing custom hdfs-site.xml to Drill's classpath?
