The MetricsSourceAdapter#getAttribute in 0.20.203 is returning the attribute object instead of the value.
This is only for the branch-0.20-security* branches. yahoo-merge and trunk do not have this bug.
Comment +1 on the patch. It looks good, some tests would be nice, but it is a single line change that really doesn't impact much. Plus it makes 0.20.20X consistent with trunk.
some tests would be nice.
Agreed. It'd be awesome if you can take up HADOOP-7273, which would help us write tests for JMX stuff outside HDFS.
I just committed this. Thanks, Luke!
