Counter names are ugly
----------------------
Key: HADOOP-1041
URL: https://issues.apache.org/jira/browse/HADOOP-1041
Project: Hadoop
Issue Type: Improvement
Components: mapred
Affects Versions: 0.12.0
Reporter: Owen O'Malley
Fix For: 0.12.0
Having the complete class name in the counter names makes them unique, but they
are ugly to present to non-developers. It would be nice to have some way to
have a nicer string presented to the user. Currently, the Enum is converted to
a name like:
key.getDeclaringClass().getName() + "#" + key.toString()
which gives counter names like
"org.apache.hadoop.examples.RandomWriter$Counters#BYTES_WRITTEN"
which is unique, but not very user friendly. Perhaps, we should strip off the
class name for presenting to the users, which would allow them to make nice
names. In particular, you could define an enum type that overloaded toString to
print a nice user friendly string.
Thoughts?
