Subject [jira] [Commented] (HDFS-3358) Specify explicitly that the NN UI status total is talking of persistent objects on heap.
Date Thu, 03 May 2012 19:56:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267750#comment-13267750

Harsh J commented on HDFS-3358:
-------------------------------

bq. Suppose someone does not understand what does it mean by "223 files and directories, 138
blocks = 361 total." It would be hard to believe that the statement suddenly becomes clear
to him/her if the magic word "objects" is added.

Well it wouldn't be clearer either way, seems like. I welcome your suggestion on how to de-confuse
in this case. I merely thought if we add in "object", admins can stop focusing on trying to
understand what it means (without gathering understanding first).

How about "filesystem objects" instead of "objects" then?

bq. You also said that "Perhaps just being explicit about java-terms would be nicer ..." So,
are you using a Java term but not talking about Java?

Heap's a pretty specific java (well, programming?) term. In accordance with that, adding "objects"
would help users ignore that. But yeah, my changes could have caused them to instead go check
jmap for object instances too, I guess. My bad in communicating here :-)

> The NN shows, on its web UI, something like:
> {{223 files and directories, 138 blocks = 361 total.}}
> Followed by heap stats.
> We should clarify this line is talking of objects and is related to the heap summaries.
Perhaps just being explicit about java-terms would be nicer:
> {{223 files and directories, 138 blocks = 361 total objects.}}
