------------------------------------
Summary: Provide a system-default EC policy
Key: HDFS-11975
URL: https://issues.apache.org/jira/browse/HDFS-11975
Project: Hadoop HDFS
Issue Type: Sub-task
Components: erasure-coding
Affects Versions: 3.0.0-alpha3
Reporter: Lei (Eddy) Xu
Assignee: SammiChen
>From the usability point of view, it'd be nice to be able to specify a
>system-wide EC policy, i.e., in {{hdfs-site.xml}}. For most of users / admin /
>downstream projects, it is not necessary to know the tradeoffs of the EC
>policy, considering that it requires the knowledge of EC, the actual physical
>topology of the clusters, and many other factors (i.e., network, cluster size
>and etc).
