creating tables in S3

Hi,

So I have a directory full of pipe separated value files. I was hoping to convert these to parquet using Drill’s CTAS command. I tried this:

create table s3.tmp.`my_table` (x, y) as SELECT COLUMNS[0] x, COLUMNS[1] y FROM s3.`path/to/my.tbl`

after a little time, I get this error:

org.apache.drill.common.exceptions.UserRemoteException: VALIDATION ERROR: Schema [s3.tmp] is not valid with respect to either root schema or current default schema. Current default schema: No default schema selected

I am able to query data from that S3 file.

This is my S3 plugin configuration:

{
"type": "file",
"enabled": true,
"connection": "s3a://my_bucket",
"config": null,
"workspaces": {
"root": {
"location": "/",
"writable": false,
"defaultInputFormat": null
},
"tmp": {
"location": "drill-tmp",
"writable": true,
"defaultInputFormat": null
}
},


I have created the directory “drill-tmp” in my bucket, and it is empty.

The file is a pipe separated value, so it does not have a schema. Does anybody know what I’m doing wrong or how to get this to work?

Hi Michael,
A few questions:
1. Does the origin query work?

SELECT COLUMNS[0] x, COLUMNS[1] y FROM s3.`path/to/my.tbl`

One thing that jumps out at me is that I think "columns" has to be lower
case.

2. Did you set up the .tbl extension to read pipe separated files? That
also could be causing problems if not.

I am wondering if location information in plugin configuration should be

"location": “/drill-tmp” (instead of “location":”drill-tmp”)


Thanks,
Padma
