### Deprecation of FlexVolume

FlexVolume is deprecated. Out-of-tree CSI driver is the recommended way to write volume drivers in Kubernetes.
See [this doc](https://github.com/kubernetes/community/blob/master/sig-storage/volume-plugin-faq.md#kubernetes-volume-plugin-faq-for-storage-vendors) for more information.
Maintainers of FlexVolume drivers should implement a CSI driver and move users of FlexVolume to CSI.

Первый параметр типа предназначен для ключей `dict`.

Второй параметр типа предназначен для значений `dict`:

{* ../../docs_src/python_types/tutorial008.py hl[1,4] *}


Это означает:

* Переменная `prices` является `dict`:
    * Ключи этого `dict` имеют тип `str` (скажем, название каждого элемента).
    * Значения этого `dict` имеют тип `float` (скажем, цена каждой позиции).

#### `Optional`

- Run the Apache Spark Pi job in yarn-client mode, using code from **org.apache.spark**:

```
./bin/spark-submit --class org.apache.spark.examples.SparkPi \
    --master yarn-client \
    --num-executors 1 \
    --driver-memory 512m \
    --executor-memory 512m \
    --executor-cores 1 \
    examples/jars/spark-examples*.jar 10
```

The job should produce an output as shown below. Note the value of pi in the output.
