Can you change the logging level to DEBUG and post the logs again.. That'll give a better idea on whats happening. You dont need to attach the logs. Use pastebin or pastie.. Those are convenient. -ak Amandeep Khurana Computer Science Graduate Student University of California, Santa Cruz On We

Thanks J-D, sorry I was slow on the uptake, now I understand exactly what you mean. Fyi I want two different machines running on my one laptop because I am writing a framework plug-in not an app and as part of the docs I am writing I have to describe how to configure my plug-in to work in an ins

Keith, This virtual Ubuntu server is for development, not for production, right? If so, try editing "/etc/hosts" of the Ubuntu server, so that it can resolve the correct IP (192.168.1.19) from its hostname. First two entries of /etc/hosts should like this: 127.0.0.1 localhost 127.0.1.1

Keith, This is exactly what I said in my first email, by default the value is localhost and the IP it points to depends on your OS config which in your case is 127.0.1.1 The thing with hbase.master is that since HBase is now capable of handling master failover, this value would only make sense if

Thank you Barney Frank, your detailed notes were very helpful in confirming I was doing things correctly already on the client. I did a lot of tracing through the HBase code and concluded that the problem lay with my server. It looks like 0.20.0 has all sorts of DNS config entries and by defaul

There could be multiple reasons for the OOME.. Getting stuck at 66% means that its stuck at going through all the values for a given key (most probably). Is there any way you can distribute the values to multiple keys? Maybe by adding some kind of an extra character to the key and then doing away w

Ok, to answer myself: to write a standalone hbase client, it seems to be enough to * set up the zookeeper server(s) to ask around: HConstants.ZOOKEEPER_QUORUM ("hbase.zookeeper.quorum") * if different from std, set the zk port "hbase.zookeeper.property.clientPort" * if different from std, ,

Hi, thx for the answers in this thread, but is there anywhere a description on how to connect from a client? I mean, before (0.20) it was enough to instantiate HTable/HBaseAdmin by just setting the master address in the configuration (as in Keith' example). Now it seems to expect a lot mor
