create hive table from tab separated file in s3 using interactive mode

Question

I've loaded tab separated files into S3 that with this type of folders under the bucket: bucket --> se --> y=2013 --> m=07 --> d=14 --> h=00

each subfolder has 1 file that represent on hour of my traffic.

I then created an EMR workflow to run in interactive mode with hive.

When I log in to the master and get into hive I run this command:

CREATE EXTERNAL TABLE se (
id bigint,
oc_date timestamp)
partitioned by (y string, m string, d string, h string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
LOCATION 's3://bi_data';

I get this error message:

FAILED: Error in metadata: java.lang.IllegalArgumentException: The bucket name parameter must be specified when listing objects in a bucket

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

Can anybody help?

UPDATE Even if I try to use string fields only, I get the same error. Create table with strings:

CREATE EXTERNAL TABLE se (
id string,
oc_date string)
partitioned by (y string, m string, d string, h string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
LOCATION 's3://bi_data';

Hive version 0.8.1.8

So, the solution is that I had two mistakes:

1. When writing only the bucket name you should have a trailing slash in the S3 path. reference here

2. The underscore is also an issue, the bucket name should be DNS compliant.

Hope I helped someone with this.
