At the moment I’ve been trying to run elasticsearch 5.2.2 as elastic user but I have been getting the following error. Use jvm.options or ES\_JAVA\_OPTS to configure the JVM ES\_HEAP\_SIZE=16G: set -Xms16G and -Xmx16G in jvm.options or add "-Xms16G -Xmx16G" to ES\_JAVA\_OPTS I have tried changing the jvm.options by altering Xms and Xmx min and max heap size and adding this line to jvm.options ES\_JAVA\_OPTS="-Xm16g -Xmx16g" ./bin/elasticsearch But still getting the same error. I was hoping someone could assist. Thanks ---

You wrote Xm instead of Xms here. Typo? ---

Hi David yes that was a typo. Even with ES\_JAVA\_OPTS="-Xms16g -Xmx16g" ./bin/elasticsearch I am still experiencing the same error. ---

Can you try: ``` ES_JAVA_OPTS="-Xms16G -Xmx16G" ./bin/elasticsearch ``` ---

Just tried again now. with ES\_JAVA\_OPTS="-Xms16G -Xmx16G" ./bin/elasticsearch Still the same issue Error: encountered environment variables that are no longer supported Use jvm.options or ES\_JAVA\_OPTS to configure the JVM ES\_HEAP\_SIZE=16G: set -Xms16G and -Xmx16G in jvm.options or add "-Xms16G -Xmx16G" to ES\_JAVA\_OPTS I also included the error but I'm unsure what that means? ---

Sounds like the env variable is still set. Can you remove it? ---

Okay how do I do that. Would I need to comment out ``` node.name: ${HOSTNAME} network.host: ${ES_NETWORK_HOST} ``` under `elasticsearch.yml` or do I need to perform another action? ---

No I meant removing `ES_HEAP_SIZE` ---

Yes I've removed `ES_HEAP_SIZE` but I still keep getting the same error. I had a look under /etc/sysconfig/elasticsearch and /etc/init.d/elasticsearch to try and understand what the env variables were. This is what I found ``` # Sets the default values for elasticsearch variables used in this script ES_USER="elasticsearch" ES_GROUP="elasticsearch" ES_HOME="/usr/share/elasticsearch" MAX_OPEN_FILES=65536 MAX_MAP_COUNT=262144 LOG_DIR="/var/log/elasticsearch" DATA_DIR="/var/lib/elasticsearch" CONF_DIR="/etc/elasticsearch" ``` Although further down I found this ``` # export unsupported variables so bin/elasticsearch can reject them and inform the user these are unsupported if test -n "$ES_MIN_MEM"; then export ES_MIN_MEM; fi if test -n "$ES_MAX_MEM"; then export ES_MAX_MEM; fi if test -n "$ES_HEAP_SIZE"; then export ES_HEAP_SIZE; fi if test -n "$ES_HEAP_NEWSIZE"; then export ES_HEAP_NEWSIZE; fi if test -n "$ES_DIRECT_SIZE"; then export ES_DIRECT_SIZE; fi if test -n "$ES_USE_IPV4"; then export ES_USE_IPV4; fi if test -n "$ES_GC_OPTS"; then export ES_GC_OPTS; fi if test -n "$ES_GC_LOG_FILE"; then export ES_GC_LOG_FILE; fi ``` ---

If you really have the same exact error message, then I believe that something, somewhere is then setting `ES_HEAP_SIZE`. I'm sorry I can't help more but you probably need to find where it has been set. It can be in a `~/.profile`, in a startup script... BTW how did you install elasticsearch? May be just download a new version (take the ZIP distribution), unzip it then just launch `bin/elasticsearch` and see what happens. Might give you a clue. ---
