This version of the Apache Knox Gateway is tested against Hortonworks Sandbox 1.2
In order to correct the issue with Sandbox you can use the commands below to login to the Sandbox VM and modify the configuration. This assumes that the name sandbox is setup to resolve to the Sandbox VM. It may be necessary to use the IP address of the Sandbox VM instead. This is frequently but not always 192.168.56.101.
ssh root@sandbox cat /usr/lib/hadoop/conf/hdfs-site.xml | sed s/localhost/sandbox/ > /usr/lib/hadoop/conf/hdfs-site.xml shutdown -r now
In addition to make it very easy to follow along with the samples for the gateway you can configure your local system to resolve the address of the Sandbox by the names vm and sandbox.
On Linux or Macintosh systems add a line like this to the end of the /etc/hosts file on your local machine, not the Sandbox VM. Note: That is a tab character between the 192.168.56.101 and the vm.
192.168.56.101 vm sandbox
On Windows systems a similar but different mechanism can be used. On recent versions of windows the file that should be modified is %systemroot%\system32\drivers\etc\hosts
The Apache Knox Gateway is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.
While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
