Your image didn't go through. You may want to upload it to image sharing site. What version of Hadoop are you using ? Thanks On Oct 6, 2013, at 8:56 PM, 남윤민 wrote: > Hello!! > My name is Yoonmin Nam from South Korea. > > Currently, I am trying to debug namenode and datanode using eclipse and

About debugging HDFS and MapReduce...

Hello!! My name is Yoonmin Nam from South Korea.Currently, I am trying to debug namenode and datanode using eclipse and fully-distributed environemnt in my lab. (1 master and 10 nodes)However, I can do debug but not fully, just some portion of source code of hadoop.This means I cannot see how so

Re: [Proposal] Pluggable Namespace

Milind, Am I missing something here? This was supposed to be a discussion and am hoping thats why you started the thread. I don't see anywhere any conspiracy theory being considered or being talked about. Vinod asked some questions, if you can't or do not want to respond I suggest you skip emai

RE: [Proposal] Pluggable Namespace

Vinod, I have received a few emails about concerns that this effort somehow conflicts with federated namenodes. Most of these emails are from folks who are directly or remotely associated with Hortonworks. Three weeks ago, I sent emails about this effort to a few Hadoop committers who are primar

RE: [Proposal] Pluggable Namespace

Vinod, Block Pool management separation makes this effort easier. Even with that separation, the namespace implementation is still embedded within the namenode, federated or otherwise. This effort is much less ambitious. All it attempts to do is allow different namespace implementation. - milind

Re: [Proposal] Pluggable Namespace

In order to make federation happen, the block pool management was already separated. Isn't that the same as this effortt? Thanks, +Vinod On Oct 6, 2013, at 9:35 AM, Milind Bhandarkar wrote: > Federation is orthogonal with Pluggable Namespaces. That is, one can use > Federation if needed, even w

RE: [Proposal] Pluggable Namespace

Federation is orthogonal with Pluggable Namespaces. That is, one can use Federation if needed, even while a distributed K-V store is used on the backend. Limitations of Federated namenode for scaling namespace are well-documented in several places, including the Giraffa presentation. HBase is onl
