Elasticsearch won't start after upgrade from 2.4.5 to 5.6

Elastic Stack Elasticsearch
1

I am trying to upgrade Elasticsearch from 2.4.5 to 5.6 on the latest Debian. I did the upgrade, and after the upgrade, Elasticsearch would not start. I have no plugins installed, so that is not an issue. I kept my elasticsearch.yml and init script. I updated the data directory, so that is not an issue. The frustrating part is there is nothing in the /var/log/elasticsearch logs or /var/log/messages. The main problem seems to center around:

ERROR: D is not a recognized option

The full output when I do service elasticsearch status is:

root@myserver:~# service elasticsearch status

Any help would be appreciated.

Whats your java version?

We are now using -E instead of -D.

Sounds like startup scripts have not been updated.

Here is my Java info:

openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-2~bpo8+1-b14)
OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode)

OK, I see it is out of date. I will upgrade it. Would this be the problem?

Hi, forgive my stupidity, but where is the -E versus -D? In the init script, elasticsearch.yml, or /etc/default/elasticsearch?

I can see that in your logs:

Process: 940 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -Des.pidfile=${PID_DIR}/elasticsearch.pid -Des.default.path.home=${ES_HOME} -Des.default.path.logs=${LOG_DIR} -Des.default.path.data=${DATA_DIR} -Des.default.path.conf=${CONF_DIR} (code=exited, status=64)

You can see there a lot of -D.

See https://www.elastic.co/guide/en/elasticsearch/reference/5.6/breaking_50_settings_changes.html#_using_system_properties_to_configure_elasticsearch

I upgraded my Java to the latest, and ran the upgrade again. I accepted the new init script, but kept my old elasticsearch.yml file. It now works. Thank you everyone.
