Sandbox Configuration

This version of the Apache Knox Gateway is tested against Hortonworks Sandbox 1.2

Currently there is an issue with Sandbox that prevents it from being easily used with the gateway. In order to correct the issue, 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
cp /usr/lib/hadoop/conf/hdfs-site.xml /usr/lib/hadoop/conf/hdfs-site.xml.orig
sed -e s/localhost/sandbox/ /usr/lib/hadoop/conf/hdfs-site.xml.orig > /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. The IP address that is shown below should be that of the Sandbox VM as it is known on your system. This will likely, but not always, be 192.168.56.101.

On Linux or Macintosh systems add a line like this to the end of the file /etc/hosts on your local machine, not the Sandbox VM.
Note: The character between the 192.168.56.101 and vm below is a tab character.

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
