[jira] [Commented] (SPARK-36024) Switch the datasource example due
to the depreciation of the dataset
[ https://issues.apache.org/jira/browse/SPARK-36024?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17426166#comment-17426166 ]
Steve Loughran commented on SPARK-36024:
----------------------------------------
Amazon are being very nice here and keeping the landsat index file for us: )
even so, it'd be good to move onto something more structured anyway, just to discourage people using .csv.gz as a persistence format

> Key: SPARK-36024
> URL: https://issues.apache.org/jira/browse/SPARK-36024
> Project: Spark
> Issue Type: Documentation
> Components: Documentation
> Affects Versions: 3.1.2
> Reporter: Leona Yoda
> Priority: Trivial
>
> The S3 bucket that used for an example in "Integration with Cloud Infrastructures" document will be deleted on Jul 1, 2021 [https://registry.opendata.aws/landsat-8/ |https://registry.opendata.aws/landsat-8/]
> The dataset will move to another bucket but it requires `--request-payer requester` option so users have to pay S3 cost. [https://registry.opendata.aws/usgs-landsat/]
>
> So I think it's better to change the datasource like this.

> I chose [NYC Taxi data| [https://registry.opendata.aws/nyc-tlc-trip-records-pds/|https://registry.opendata.aws/nyc-tlc-trip-records-pds/),]] here for an example.
> Unlike landat data it's not compressed, but it is just an example and there are several tutorials using Spark (e.g. [https://github.com/aws-samples/amazon-eks-apache-spark-etl-sample)]

> Reed test result
