Just realized that running on a proxy on each tserver is probably a bad idea. It make the user of the thrift API have to handle failure cases (i.e. remote proxy I was using failed, now I need to select another). If you are running a local proxy process, there could be failures but I think its much less likely. Using a local proxy and letting the Accumulo client code handle remote failures seems like a good way to go. - kturner ----------------------------------------------------------- This is an automatically generated e-mail.
