title: AWS Glue does not detect partitions and creates 1000+ tables in catalog
body: <p>I am using AWS Glue to create metadata tables.</p>
  <p>AWS Glue Crawler data store path: s3://bucket-name/</p>
  <p>Bucket structure in S3 is like</p>
  <pre><code>├── bucket-name        
  │   ├── pt=2011-10-11-01     
  │   │   ├── file1                    
  |   |   ├── file2                                        
  │   ├── pt=2011-10-11-02               
  │   │   ├── file1          
  │   ├── pt=2011-10-10-01           
  │   │   ├── file1           
  │   ├── pt=2011-10-11-10
