    <p>You manage files directly using Hive Table commands</p> <p>Firstly if you want to use external data controlled outside Hive use the External Command when creating the table</p> <pre><code>set S3Path='s3://Bucket/directory/'; CREATE EXTERNAL TABLE IF NOT EXISTS S3table ( data STRING ) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LOCATION ${hiveconf:S3Path}; </code></pre> <p>You can now insert data into this table</p> <pre><code> INSERT OVERWRITE TABLE S3table SELECT data FROM DynamoDBtable; </code></pre> <p>This will create text files in S3 inside the directory location Note depending on the data size and number of reducers there may be multiple text files. Files names are also random GUID element i.e. 03d3842f-7290-4a75-9c22-5cdb8cdd201b_000000</p> <pre><code>DROP TABLE S3table; </code></pre> <p>Dropping the table just breaks the link to the files</p> <p>Now if you want to manage the directory you can create a table that will take control of the S3 directory (Note there is no <code>external</code> command)</p> <pre><code>CREATE TABLE IF NOT EXISTS S3table ( data STRING ) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LOCATION ${hiveconf:S3Path}; </code></pre> <p>If you now issue a drop table command all files in the folder are delete immediately</p> <pre><code>DROP TABLE S3table; </code></pre> <p>I suggest you create a non external table then drop it and carry on with the rest of your script. If you encounter errors you will have a blank directory after the job finishes</p> <p>Hope this covers what you need</p>

    1. COI get what you are saying and added the changes to the end of my post above. However because I'm mapping dynamo columns to the table I don't think I can set the location at the same time. At any rate I get this error - mismatched input 'STORED' expecting EOF near ''s3://...Backup''

    2. COI would need to drop the table first then create it. However I can't dreate it in 1 step. From what you say I create a table. But I need to insert data into that table. If that fails then I want to delete it.

    3. COOk then to drop the table do the following set S3Path='s3://Bucket/directory/'; CREATE EXTERNAL TABLE IF NOT EXISTS S3table ( data STRING ) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LOCATION ${hiveconf:S3Path}; DROP TABLE S3table; then you can carry as you before creating your table dynamically CREATE TABLE IF NOT EXISTS DynamoDBDataBackupPreferenceStore....

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
