Re: How can I get FSNamesystem of running NameNode in cluster?

Hi Yoonmin, Yes, your conclusions here are correct. The FSNamesystem is an object internal to the NameNode server runtime. On Mon, Dec 9, 2013 at 8:49 PM, Yoonmin Nam wrote: > Oh, I see. However a minicluster cannot replace the namenode, right? > I knew that the minicluster is for testing compon

Thanks for clarifying that Arpit. I'm a +0.9 since I haven't reviewed enough to +1, but everything thus far looks great. Andrew On Fri, Dec 6, 2013 at 5:35 PM, Chen He wrote: > +1 nice feature for HDFS > > > On Fri, Dec 6, 2013 at 7:32 PM, Arpit Agarwal >wrote: > > > Hi Andrew, > > > > Our pl

RE: How can I get FSNamesystem of running NameNode in cluster?

Oh, I see. However a minicluster cannot replace the namenode, right? I knew that the minicluster is for testing components of hadoop. Then, the only way of implementing some features which use namenode or datanode is just in internal of namenode or datanode. Am I right? Thanks! -Original Me

Re: How can I get FSNamesystem of running NameNode in cluster?

Are you adding something internal to the NN? If not, you cannot get the namesystem instance via a client unless you are using a minicluster object. Daryn On Dec 9, 2013, at 7:11 AM, Yoonmin Nam wrote: > I want to get a running instance of FSNamesystem of HDFS. However, it is > somewhat compli

How can I get FSNamesystem of running NameNode in cluster?

I want to get a running instance of FSNamesystem of HDFS. However, it is somewhat complicated than I expected. If I can get NameNode instance of running cluster, then it can be solved because there is a method "getNamespace()". Is there anyone who know about this stuff? I thought that using Ser
