Subject Re: Issue connecting to ECS from Drill
Date Thu, 12 Mar 2020 06:01:47 GMT
Hi Arun,

Charles commented on the Drill version; here I'll assume you are actually using Drill 1.17.
Hard to diagnose the issue remotely. Here are a few things to double-check.

The message does look odd, do you really have a user named ":doesBucketExist"? Not sure where
Drill got this user from. Searching the source code, this message occurs when Drill does a
"do as" with a user defined, it seems, defined by the Hadoop proxy user system. Does your
core-site.xml file contain the definition of a proxy user? See documentation at [1].

Does your core-site.xml file contain the entries from the Drill docs? [2] And only those entries
(no other entries copied from some other Hadoop-based file?)

Is the file named "core-site.xml" and is it in your Drill conf directory? Or, if you are using
a separate "site" directory, is it in the site's conf directory?

If using core-site.xml, did you remove the corresponding properties from the JSON storage
plugin config?

Do these same credentials work with the AWS script to access S3?

We are running Drill 1.7 in embedded mode and trying to connect to ECS using s3 plugin. We
tried having the config in both plugin and core-site.xml but doesn’t work and gives below

Validation error: Failed to create DrillFileSystem for proxy user :doesBucketExist on ...

Please can someone give pointers? Appreciate any help. Thanks.
