This notice is to inform the community that the following features are deprecated in 5.5.0 and will be removed in 6.0:
- We will no longer be testing or developing against Hadoop 1.x versions. As of 6.0 those versions will be untested and unsupported. Use them at your own risk.
- The Elasticsearch on Apache YARN Beta
If there are any questions or concerns over these deprecations, please feel free to discuss them on these forums.
Edit: Previously this post mentioned deprecations of the "old" mapred api. Those deprecations are erroneous. We will continue to support the "old" mapred api for as long as it is a stable component of Hadoop.
