== UPDATE ==
 +
 +
I update the catalog to include the cosmos_2015_dr_2_1 index to be able to make joins directly in COSMOHUB.
 +
 +
To do the matching I use a python notebook which can be found here:
 +
 +
> /nfs/pic.es/user/j/jcarrete/python_notebooks/Matching_ZEST_and_COSMOS2015.ipynb
 +
 +
I create a table with the "link" (`sequentialid`, `cosmos2015_id):
 +
 +
<pre>
 +
CREATE EXTERNAL TABLE jcarrete.zest_cosmos2015_spatial_matching_csv (
 +

UPDATE

I update the catalog to include the cosmos_2015_dr_2_1 index to be able to make joins directly in COSMOHUB.

To do the matching I use a python notebook which can be found here:

> /nfs/pic.es/user/j/jcarrete/python_notebooks/Matching_ZEST_and_COSMOS2015.ipynb

I create a table with the "link" (`sequentialid`, `cosmos2015_id): 

CREATE EXTERNAL TABLE jcarrete.zest_cosmos2015_spatial_matching_csv (
sequentialid int,
ra float,
dec float,
cosmos2015_id bigint,
cosmos2015_distance float
)
ROW FORMAT SERDE 
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'

LOCATION
  'hdfs://namenode01/user/jcarrete/data/zest_cosmos2015_spatial_matching/'
