Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

Sample service script for debianoids

Look at LSB init scripts for more information.

Usage

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)

Serialization

As all objects must be Serializable to be used as part of RDD operations in Spark, it can be difficult to work with libraries which do not implement these featuers.

Java Solutions

Simple Classes

For simple classes, it is easiest to make a wrapper interface that extends Serializable. This means that even though UnserializableObject cannot be serialized we can pass in the following object without any issue

public interface UnserializableWrapper extends Serializable {
 public UnserializableObject create(String parm1, String parm2);

Delete all containers
```
 $ docker ps -q -a | xargs docker rm
```

-q prints only the container IDs -a prints all containers

Notice that it uses xargs to issue a remove container command for each container ID

Delete all untagged images

	#Delete stopped (exited) containers:

	docker ps --no-trunc -aqf "status=exited" \| xargs docker rm

	#Delete unused (dangling) images:

	docker images --no-trunc -aqf "dangling=true" \| xargs docker rmi
