# AWS ParallelCluster version 2

{% hint style="info" %}
This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/aws-parallelcluster-user-guide.git)

## Development

* **Important**\
  The following sections include instructions for using a custom version of the cookbook recipes and a custom AWS ParallelCluster node package. This information covers an advanced method of customizing AWS ParallelCluster, with potential issues that can be hard to debug. The AWS ParallelCluster team highly recommends using the scripts in [Custom Bootstrap Actions](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_parallel_cluster/pre_post_install.md) for customization, because post-install hooks are generally easier to debug and more portable across releases of AWS ParallelCluster.

## Troubleshooting

* **Note**\
  Starting with version 2.11.5, AWS ParallelCluster doesn't support the use of SGE or Torque schedulers.
