Subject Hadoop 2.2.0 YARN isolation and Windows
Date Thu, 09 Jan 2014 21:19:33 GMT

Three questions about the new Hadoop release regarding YARN:

1. Does YARN need to run on the same machines that are hosting the HDFS
services or can HDFS be remote of a YARN cluster? If this done by placing
the remote HDFS cluster's configuration files (core-site.xml and
hdfs-site.xml) on the YARN cluster's machines?

2. According to
Hadoop 2.2.0 supports Microsoft Windows. How do/Can you configure YARN for
secure container isolation in Windows? It seems that the ContainerExecutor
and DefaultContainerExecutor can detect and run on Windows, but the secure
LinuxContainerExecutor are for *nix systems, so is there anything in place
for maximum security like LCE is?

3. If 1 is yes, then is it possible to have a cluster mixed with both Linux
and Windows machines running YARN and working together?
