Subject Getting hostname (or any environment variable) into *-site.xml files
Date Fri, 12 Oct 2012 13:37:55 GMT
Hi,
   We are using a library with hdfs that uses custom properties inside the
*-site.xml files.  Instead of (a) hard-coding or (b) writing a "sed" script
to update to the local hostnames on each deployed node, is there a
mechanism to use environment variables?

<property>
<name>custom.property</name>
<value>${HOSTNAME}</value>
</property>


I have tried this and out of the box the string ${HOSTNAME} is used.
 Anyone have recommendation/solution on this?

thanks,

stephen b
