Why is the configuration location '/usr/share/elasticsearch/config', not '/etc/elasticsearch' ?

[erictt]

I've checked the document : https://www.elastic.co/guide/en/elasticsearch/reference/5.0/deb.html#deb-layout

It says, default configuration locations is /etc/elasticsearch, but why is it deferent in Docker?
I didn't see any updates in the Dockerfile.

And the tricky problem is x-pack configurations doesn't work if i put them under /usr/share/elasticsearch/config.

That only happens when using the init script:

NAME=elasticsearch
...
CONF_DIR=/etc/$NAME
...
DAEMON_OPTS="-d -p $PID_FILE -Edefault.path.logs=$LOG_DIR -Edefault.path.data=$DATA_DIR -Edefault.path.conf=$CONF_DIR"`

We run elasticsearch directly so it runs in the foreground, since there is no init system running in the container. Thus, we just get the default config directory in the install directory.

If your Elasticsearch can't find hunspell dictionaries because there is no /etc/elasticsearch folder - just create folder with your hands sudo mkdir -p /etc/elasticsearch/hunspell
I don't know why, but ES is looking for hunspell only in /etc/elasticsearch
