Re: hbase is not starting

(sending to @user since it's not a dev question, bcc'ing the latter) So the important part is: Unhandled exception. Starting shutdown. java.lang.NoClassDefFoundError: org/apache/commons/configuration/Configuration And it seems to be coming from the hadoop security stack. From what I can tell

Re: integrate hbase over hadoop in eclipse IDE

Hi Vamshi, Are you launching HBase from eclipse or from the standard scripts? The stacktrace shows something is wrong while HMaster tries to connect Hadoop, and Hadoop checks the security. I'm confused by the java.lang.NoClassDefFoundError:org/apache/commons/configuration/Configuration

Secure Hadoop and non-secure HBase

Hi all, Hortonworks has a patch for secure append for Apache Hadoop 0.20.205 to work with HBase 0.90.x. However, secure Hadoop and HBase would work until kerberos token expires. There is currently no code that renews kerberos token in HBase. Hence, it is possible to add a cron job to

Hi Eric, Could you please explain more fully what you mean by this? The daemons generally run using keytabs, not user credentials, and thus shouldn't need the explicit TGT Renewer, right? -Todd On Sun, Sep 11, 2011 at 11:04 AM, Eric Yang eric...@gmail.com wrote: Hi all, Hortonworks has a

Re: Secure Hadoop and non-secure HBase

Hi Eric, If you configure hbase.master.keytab.file hbase.master.kerberos.principal hbase.regionserver.keytab.file hbase.regionserver.kerberos.principal in your hbase-site.xml, then the master and region server processes should login from the keytab files on startup, as Todd mentions. It's also

Hi Gary, This is exactly what I missed. Without those settings in my hbase-site.xml, I saw these messages in regional server log file: 2011-09-09 17:28:14,172 WARN org.apache.hadoop.ipc.Client: Couldn't setup connection for hb...@test.example.com
