Hi

We had earlier version(1.75) of ES running and now we are trying to upgrade to 5,2 as per the upgrade guidelines. I'm trying to set up a parallel cluster and getting below Error while starting ES:

Error: encountered environment variables that are no longer supported  
use jvm.options or ES\_JAVA\_OPTS to configure the JVM  
ES\_HEAP\_SIZE=4g: set -Xms4g and -Xmx4g in jvm.options or add @-Xms4g -Xmx4g@ to ES\_JAVA\_OPTS

Although, jvm.options file already contains these setting by default.

Please suggest what needs to be done.
