kandi X-RAY | spark-tutorial Summary

spark-tutorial is a Python library typically used in Telecommunications, Media, Media, Entertainment, Big Data, Spark applications. spark-tutorial has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

The idea of this tutorial is to show how code can be shared between streaming and batch analysis in pyspark (see the functions in analysis.py). The focus is maintenance of the code in the long term, i.e. you want to update your analysis functions, without affecting both streaming and batch pipelines. Batch is currenty showing 2 use cases: 1. relaunch hashtag analysis — think you want to have data on a specific temporal window 1. recompute keywords and relaunch analysis — think you have an improved algorithm and need to update all historical data. This is a work in progress. TODO: - storage (relations, update) - a consumer, like a web ui? - refactoring - better use of cluster.

Looking at the source of the error (worker.py#L25), it seems that the python interpreter used to instanciate a pyspark worker doesn't have access to the resource module, a built-in module referred in Python's doc as part of "Unix Specific Services".

Are you sure you can run pyspark on Windows (without some additional software like GOW or MingW at least), and so that you didn't skip some Windows-specific installation steps ?

Could you open a python console (the one used by pyspark) and see if you can >>> import resource without getting the same ModuleNotFoundError ? If you don't, then could you provide the ressources you used to install it on W10 ?

QUESTION

If I already have Hadoop installed, should I download Apache Spark WITH Hadoop or WITHOUT Hadoop?

Asked 2018-Apr-23 at 07:05

I already have Hadoop 3.0.0 installed. Should I now install the with-hadoop or without-hadoop version of Apache Spark from this page?

I am following this guide to get started with Apache Spark.
It says

Download the latest version of Apache Spark (Pre-built according to your Hadoop version) from this link:...

But I am confused. If I already have an instance of Hadoop running in my machine, and then I download, install and run Apache-Spark-WITH-Hadoop, won't it start another additional instance of Hadoop?

...

ANSWER

First off, Spark does not yet support Hadoop 3, as far as I know. You'll notice this by no available option for "your Hadoop version" available for download.

You can try setting HADOOP_CONF_DIR and HADOOP_HOME in your spark-env.sh, though, regardless of which you download.

You should always download the version without Hadoop if you already have it.

won't it start another additional instance of Hadoop?

No. You still would need to explicitly configure and start that version of Hadoop.

That Spark option is already configured to use the included Hadoop, I believe
