Sample format include "512m", and "10g". +# +# ES_HEAP_SIZE -- Sets both the minimum and maximum memory to allocate (recommended) +# +# As a convenience, a fragment of shell is sourced in order to set one or +# more of these variables. This so-called `include' can be placed in a +# number of locations and will be searched for in order. The lowest +# priority search path is the same directory as the startup script, and +# since this is the location of the sample in the project tree, it should +# almost work Out Of The Box. +# +# Any serious use-case though will likely require customization of the +# include. For production installations, it is recommended that you copy +# the sample to one of /usr/share/elasticsearch/elasticsearch.in.sh, +# /usr/local/share/elasticsearch/elasticsearch.in.sh, or +# /opt/elasticsearch/elasticsearch.in.sh and make your modifications there. +# +# Another option is to specify the full path to the include file in the +# environment.
