---------------------------------------
Hi, The issue resolved.
I was using DRILL in embeded mode. I tried with storage plugin as:-
"connection": "hdfs://localhost:54310/",
Earlier I was getting connection error. I restarted "HADOOP" and then tried
again, and it worked.
I am not sure why hadoop needs to be restarted. I haven't changed any
configurations.
The issue can be closed now.

> 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,

> "hdfs://192.168.108.133:8020/",
> Now when I am checking data from DRILL Explorer, its giving connection error.
