Jason Lowe reopened HADOOP-10468:
---------------------------------
Reopening this issue as it breaks all existing metrics2 property files. Before
this change the properties needed to be lower-cased but now they must be
camel-cased (e.g.: namenode.* now must be NameNode.*).
The release note states that the metrics2 file became case-sensitive, but I
don't believe that's the case. MetricsConfig uses
org.apache.commons.configuration.SubsetConfiguration which I think has always
been case-sensitive.
I'm hoping there's a way we can fix the underlying issue without breaking
existing metrics2 property files, because the way in which they break is
silent. The settings are simply ignored rather than an error being thrown for
unrecognized/unhandled properties.
