I'm not sure what that file is really used for, there are no references to it
in the code (if I search on gluster-env)
{quote}
Ideally gluster-env file should be exposed on the UI for reconfiguration and it
should get created/updated on the machines if GLUSTERFS is
installed/reconfigured in a cluster. That will fix this issue
{quote}
I think the bigger question or real issue is, shouldn't the
/etc/hadoop/conf/hadoop-env.sh file get freshly written/updated on each cluster
install/deploy?

hadoop-env.xml is a configuration file of HDFS service package in HDP-2.0.6
stack (parent stack to 2.1.GlusterFS stack). [link to file |

This subsequently translates in the HDP-2.0.6 stack shared initialization
scripts to create hadoop-env.sh file only if HDFS/NameNode is a part of the
cluster. [code pointer |
