> I tried to setting ES\_HEAP\_SIZE to 1024m on my linux server. I used this setting \> export ES\_HEAP\_SIZE=1024m. Now how to check if this new setting is work??

Look at the resulting JVM process when you start ES, specifically the -Xmx option.

If you're starting ES as a service (which you should be doing) you should probably be modifying /etc/sysconfig/elasticsearch or /etc/default/elasticsearch instead.
