Dynamic mapping allow to dynamically introduce new fields into an existing mapping. There is a (pretty rare) race condition, where a new field/object being introduced will not be immediately visible for another document that introduces it at the same time.

There is no need to write the pidfile in the bin/elasticsearchshell script
as this happens already in the java code.
Also cleaning up the bin/elasticsearch shell script a bit (no need to return
an error code when exec is called, as this forks and exits the shell script
immediately).
Closes#3529Closes#1745
Currently the bin/plugin command did not allow one to set jvm parameters
for startup. Usually this parameters are not needed (no need to configure
heap sizes for such a short running process), but one could not set the
configuration path. And that one is important for plugins in order find
out, where the plugin directory is.
This is especially problematic when elasticsearch is installed as
debian/rpm package, because the configuration file is not placed in the
same directory structure the plugin shell script is put.
This pull request allows to call bin/plugin like this
bin/plugin -Des.default.config=/etc/elasticsearch/elasticsearch.yml -install mobz/elasticsearch-head
As a last small improvement, the PluginManager now outputs the directort
the plugin was installed to in order to avoid confusion.
Closes#3304
This decision helps people who want to rollout the oracle java without having an openjdk java installed.
* Removed any hard dependency on Java in the debian package
* The debian init script does not check for an existing JAVA_HOME anymore
* Debian and RedHat initscripts now exit if they do not find a java binary (instead of starting elasticsearch in the background and swallowing the error as there is no way to log it in that case)
* Changed the debian init script to rely on the pid file instead of the argument name of process
* Added a useful error message in case no java binary is available (in elasticsearch shell script)

It's easier to manage a configuration through environment variables than
through a config file if that config file has static values that need to
change each version (such as the ES_CLASSPATH). Trying to keep that in
Chef is tedious whereas just controlling these few settings with
environment variables like most of the other settings in here is simple
and straightforward.
Summary:
Facebook machines have on direct access to the internet. Need to tell java that we should use proxies.
Test Plan:
export JAVA_OPTS="-Dhttp.proxyHost=<ip> -Dhttp.proxyPort=8080"
