Can you please share the full error message (please see [1]) Also, can you please see if this works: show files in dfs.tmp; This is to check if the DFS plugin is successfully initialized and Drill can see the files on HDFS. And if that works, check if simpler queries on the data works: select * from hdfs.`<path_to_table>`
