-------------------------------------

HDFS-1620 has caused a fair bit of strife - was it really worth it?

> HDFS-1620 renamed FSConstants which we believed to be a private class. But currently the public APIs for safe-mode and datanode reports depend on constants in FSConstants. This is breaking HBase builds against 0.23. This JIRA is to provide a backward-compatibility route.
