Miscellaneous notes about Apache Solr and Apache Ranger. I typically increase number of shards from 1 to at least 5 (this is done in the above curl CREATE command).. Solr only supports an absolute max of ~2 billion (size of int) documents in a single shard due to Lucene max shard size.

Knox Apache Knox ( GitHub repo) is an HTTP reverse proxy, and it provides a single endpoint for applications to invoke Hadoop operations. It supports multiple clusters and multiple components like webHDFS, Oozie, WebHCat, etc. Overview. All HDFS commands are invoked by the bin/hdfs script. Running the hdfs script without any arguments prints the description for all commands. Usage: hdfs [SHELL_OPTIONS] COMMAND [GENERIC_OPTIONS] [COMMAND_OPTIONS] Hadoop has an option parsing framework that employs parsing generic options as well as running classes. However, an extra layer of security in the cloud requires a special toolkit to access the BigInsights service in Bluemix. The HDFS for Bluemix toolkit contains Streams operators that can connect through the Knox Gateway. This article shows how to use these operators to read and write files to HDFS on Bluemix. Hortonworks Data Platform (HDP) 2.3 represents the latest innovation from across the Hadoop ecosystem, especially in the area of security. With HDP 2.3, enterprises can secure their data using a gateway for perimeter security, provide fine grain authorization and auditing for all access patterns, and ensure data encryption over the wire as well as stored on disk.

Apache Knox — to serve as a single point for applications to access HDFS, Oozie, and other Hadoop services. Figure 3: Enhanced user experience with Hue, Zeppelin, and Knox. We will describe each product, the main use cases, a list of our customizations, and the architecture. Hue. Hue is a user interface to the Hadoop ecosystem. the big data architecture. HDP provides valuable tools and capabilities for every role on your big data team. The data scientist Apache Spark, part of HDP, plays an important role when it comes to data science. Data scientists commonly use machine learning, a set of techniques and algorithms that can learn from data. One of the main reasons to use Apache Knox is the isolate the Hadoop cluster from direct connectivity by users. Below, we demonstrate how you can interact with several Hadoop services like WebHDFS, WebHCat, Oozie, HBase, Hive, and Yarn applications going through the Knox endpoint using REST API calls. End to End Wire Encryption with Apache Knox a Hadoop cluster can now be made securely accessible to a large number of users. Today, Knox allows secure connections to Apache HBase, Apache Hive, To get around this, export the certificate and put it in the cacerts file of the JRE used by Knox.
