Lets say I had a mapping like this,

192.168.0.2 -> /rackdefault
I would now like to map

192.168.0.2 -> /rack02

What is the procedure to do this? is this possible to do while the
cluster is running?

TIA

No.  There is a jira i filed on turning the cache into an actual cache w/TTLs, etc.

https://issues.apache.org/jira/browse/HDFS-870, for those who like
hyperlinks.

Links are always appreciated as I feed here my semantic network
about MapReduce/Hadoop/... with them:

So if you have the feeling that your favourite tool is
underrepresented there, feel free to provide me with more material.

Thanks.

What is 'JT'? JobTracker?
