EC configuration in file header as one storage policy. We have discussed and [concluded |https://issues.apache.org/jira/browse/HDFS-7285?focusedCommentId=14296210&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14296210]

HDFS-7337 will add configurable and pluggable schema info.
> This JIRA will follow the [plan | https://issues.apache.org/jira/browse/HDFS-7285?focusedCommentId=14370307&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14370307]
