Subject [jira] Commented: (HADOOP-2447) HDFS should be capable of limiting the total number of inodes in the system

Sameer Paranjpye commented on HADOOP-2447:
------------------------------------------

Getting the stats in the web UI would be awesome.

Do we know how efficient calls to Runtime.getTotalMemory() etc. are? Are they as trivial as
checking a couple of counters like this paths does?

> The HDFS Namenode should be capable of limiting the total number of Inodes (files + directories).
The can be done through a config variable, settable in hadoop-site.xml. The default should
be no limit.
