I will add sample usages for various libraries in GitHub in following repositories. You can follow the readmes to get started with them easily.
Continuous Integration (CI) is a development practice that requires developers to integrate code early and often. Code is integrated into a shared repository several times a day. Each check-in is then verified by an automated build, thus providing fast and automated feedback on the correctness of your application every time there is a change of code.
ZooKeeper is an application library that allows distributed processes to coordinate with each other through a shared hierarchical name space of data registers; these data registers are called as znodes.
ZooKeeper was designed to store coordination data such as status information, configuration, location information, and so on.
ZooKeeper was a sub-project of Hadoop but is now a top-level project in its own right.
With the previous notes from the current book (Amazon Elasticsearch Service) and Elasticsearch Essentials, you should have decent understanding of Elasticsearch. Next, we will try to learn Amazon ES in deep.
Following are some of the links that will help start that journey to master Amazon ES:
Java programmers had two choices when communicating with Elasticsearch: they could use either the REST API over HTTP, or the internal Java API (aka transport client), which is used by Elasticsearch itself for node-to-node communication. When using the HTTP rest client, Elasticsearch parses the JSON to Java objects and then use the internal Java API, and when we use the internal Java API we use those internal Java objects directly.
Elasticsearch is a highly scalable open-source full-text search and analytics engine. It allows you to store, search, and analyze big volumes of data quickly and in near real time. It is generally used as an engine that powers applications that have complex search features and requirements. (source = elastic.co).
Elasticsearch provides a full Query DSL based on JSON to define queries. The behaviour of a query clause depends on whether it is used in query context or in filter context.
In Query context, besides deciding whether or not the document matches, the query clause also calculates a _score representing how well the document matches, relative to other documents. Here, a query clause is passed to a query parameter, such as the query parameter in the search API.
To show only running containers:
docker ps
or
docker container ps
To show all containers:
docker ps -a
or
docker container ps -a
To show the latest created container (includes all states):
docker ps -l
To show n last created containers (includes all states):
docker ps -n=-1
Datasets are needed for practicing and learning most big data technologies. Here are few datasets that may be useful for ElasticSearch. It may be useful for other big data technologies as well.

CloudMaterials is my blog to share notes and learning materials on Cloud and Data Analytics. My current focus is on Microsoft Azure and Amazon Web Services (AWS).
I like to write and I try to document what I learn to share with others. I believe that knowledge is useless unless you share it; the more you share, the more you learn.
