Apache Drill: table not found on s3 bucket - amazon-s3

Question

I'm a newbye with Apache Drill.
The scenario is this:
I've an S3 bucket, where I place my csv file called test.csv.
I've install Apache Drill with instructions from official website.
I followed this tutorial: https://drill.apache.org/blog/2014/12/09/running-sql-queries-on-amazon-s3/ for create an S3 plugin.
I start Drill, use the correct "workspace" (with: use my-s3;), but when I try to select records from test.cav file an error occured:
Table 's3./test.csv' not found.
Can anyone help me?
Thanks!

Answer 1

Use the name of your workspace (if you use one) and back ticks in the USE command as follows:
USE `my-s3`.`<workspace-name>`;
SHOW files; //should list test.csv file
SELECT * FROM `test.csv`;
Query the CSV in the local file system using the dfs storage plugin configuration to rule out things like a header causing a problem. This page might help if you haven't seen it.
Storage plugin mentioned in comment above:
{
"type": "file",
"enabled": true,
"connection": "s3n://<accesskey>:<secret>#catpaws",
"workspaces": {},
"formats": {
"psv": {
"type": "text",
"extensions": [
"tbl"
],
"delimiter": "|"
},
"csv": {
"type": "text",
"extensions": [
"csv"
],
"delimiter": ","
},
"tsv": {
"type": "text",
"extensions": [
"tsv"
],
"delimiter": "\t"
},
"parquet": {
"type": "parquet"
},
"json": {
"type": "json"
}
}
}
Probably, this is not relevant. It's an excerpt from the Amazon S3 help, which contains lots more info:
<property>
<name>fs.s3.awsAccessKeyId</name>
<value>ID</value>
</property>
<property>
<name>fs.s3.awsSecretAccessKey</name>
<value>SECRET</value>
</property>
