> Hello,
> I am new to Apache Drill and need some help. I am able to connect to Local File systema
nd Hive and query the files/ tables respectively.
> But I want to access file on Hadoop. For that I created a new Storage Plugin, (copied
from default dfs) as "hadoop" and changed connection as:
> "connection": "file:///",  ß-----------  "connection" : "hdfs://192.168.108.133:8020/",
> Now when I am checking data from DRILL Explorer, its giving connection error.
> I tried to run query after selecting: 
> use hadoop;
> 0: jdbc:drill:zk=local> select * from hadoop.`/user/hduser/drill_1.csv`;
> Oct 16, 2015 9:35:15 PM org.apache.calcite.sql.validate.SqlValidatorException <init>
