Hi,
@Mirko: Please file a JIRA. This seems an appropriate time.
@Steve: If we store the absolute filenames (i.e. the whole path), would we
still have the problem you outlined in the 2nd para? I do agree updating
would have to be pushed out and that might be cumbersome, but hey, we are
processing
One of the issues here is keeping that list up to date. You don't want
filename operations on the NN to push out changes to datanodes (which
may not be there, after all), and you don't necessarily want every block
creation operation on a DN to force an update on what effectively
becomes a min
There is also some work underway to add in HA and failover to the namenode.
You might get more success if you send your note to hdfs-dev instead of
common-dev. One other thing that can sometimes get a discussion going is to
just file a JIRA for it. People interested in it are likely to start
Hi Mirko,
Its seems like a great idea to me!! The architects and senior developers
might have some more insight on this though.
I think part of the reason why the community might be lazy about
implementing this is because the Namenode being a single point of failure is
usually regarded as FUD. Th
