Get Size of Tables on HDFS

Things on this page are fragmentary and immature notes/thoughts of the author. Please read with your own judgement!

The HDFS Way

You can use the hdfs dfs -du /path/to/table command or hdfs dfs -count -q -v -h /path/to/table to get the size of an HDFS path (or table). However, this only works if the cluster supports HDFS. If a Spark cluster exposes only JDBC/ODBC APIs, this method does not work.
