+ <p>
+
+<b>Date: </b> 21 Apr 2021<br>
+
+</p>
+
+<h2 id="overview">Overview</h2>
+
+<p>First introduced in Java 9, <a
href="https://docs.oracle.com/javase/9/jshell/introduction-jshell.htm#JSHEL-GUID-630F27C8-1195-4989-9F6B-2C51D46F52C8";>JShell</a>
is an interactive Read-Evaluate-Print-Loop (REPL)
+Java tool that interprets user’s input and outputs the results. This tool
provides a convenient
+way to test out and execute quick tasks with Accumulo in the terminal. This
feature is a part
+of the upcoming Accumulo 2.1 release. If you’re a developer and want to get
involved in testing,
+<a href="https://accumulo.apache.org/contact-us/";>contact us</a> or review our
<a href="https://accumulo.apache.org/how-to-contribute/";>contributing
guide</a>.</p>
+
+<h2 id="major-features">Major Features</h2>
+<ul>
+ <li>
+ <p>Default JShell script provides initial imports for interacting with
Accumulo’s API and
+provided in Accumulo’s binary distribution tarball</p>
+ </li>
+ <li>
+ <p>On startup, JShell Accumulo will automatically import the <code
class="language-plaintext highlighter-rouge">CLASSPATH</code>, load in a
configured
+environment from user’s <code class="language-plaintext
highlighter-rouge">conf/accumulo-env.sh</code>, and invoke <code
class="language-plaintext highlighter-rouge">conf/jshell-init.jsh</code>
+to allow rapid Accumulo task executions</p>
+ </li>
+ <li>
+ <p>JShell Accumulo can startup using default/custom JShell script and
users can append any JShell
+command-line <a
href="https://docs.oracle.com/javase/9/tools/jshell.htm#JSWOR-GUID-C337353B-074A-431C-993F-60C226163F00";>options</a>
to the startup command</p>
+ </li>
+</ul>
+
+<h2 id="booting-up-jshell-accumulo">Booting Up JShell Accumulo</h2>
+<p>1) Open up a terminal and navigate to Accumulo’s installation directory</p>
+
+<p>2) To startup JShell with <strong>default script</strong> use this
command:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre
class="highlight"><code><span class="nv">$ </span>bin/accumulo jshell
+</code></pre></div></div>
+<p>3) To startup JShell with <strong>custom script</strong> use this
command:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre
class="highlight"><code><span class="nv">$ </span>bin/accumulo jshell <span
class="nt">--startup</span> file/path/to/custom_script.jsh
+</code></pre></div></div>
+<p><strong>Note:</strong> One can execute the <code class="language-plaintext
highlighter-rouge">jshell</code> command to startup JShell. However, doing so
will require
+manually importing the <code class="language-plaintext
highlighter-rouge">CLASSPATH</code> and the configured environment from <code
class="language-plaintext highlighter-rouge">conf/accumulo-env.sh</code>
+and manually specifying the startup file for <code class="language-plaintext
highlighter-rouge">conf/jshell-init.jsh</code> before any Accumulo tasks
+can be performed. Using one of the startup commands above will automate that
process
+for convenience.</p>
+
+<h2 id="jshell-accumulo-default-script">JShell Accumulo Default Script</h2>
+<p>The auto-generated <code class="language-plaintext
highlighter-rouge">jshell-init.jsh</code> is a customizable file located in
Accumulo’s installation
+<code class="language-plaintext highlighter-rouge">conf/</code> directory.
Inside, <code class="language-plaintext
highlighter-rouge">jshell-init.jsh</code> contains <a
href="https://accumulo.apache.org/api/";>Accumulo Java APIs</a>
+formatted as import statements and <a
href="https://www.javadoc.io/doc/org.apache.accumulo/accumulo-core/latest/org/apache/accumulo/core/client/AccumuloClient.html";>AccumuloClient</a>
build implementation. On startup,
+the script automatically loads in the APIs and attempts to construct a client.
Should additional
+APIs and/or code implementations be needed, simply append them to <code
class="language-plaintext highlighter-rouge">jshell-init.jsh</code>.
+Alternatively, you can create a separate JShell script and specify the custom
script’s file path
+on startup.</p>
+
+<p>To construct an <a
href="https://www.javadoc.io/doc/org.apache.accumulo/accumulo-core/latest/org/apache/accumulo/core/client/AccumuloClient.html";>AccumuloClient</a>,
the provided <code class="language-plaintext
highlighter-rouge">conf/jshell-init.jsh</code> script finds
+and uses <code class="language-plaintext
highlighter-rouge">accumulo-client.properties</code> in Accumulo’s class path,
and assigns the result
+to a variable called <strong>client</strong>.</p>
+
+<p>If <code class="language-plaintext
highlighter-rouge">accumulo-client.properties</code> is found, a similar result
will be produced below:</p>
+
+<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre
class="highlight"><code>Preparing JShell for Apache Accumulo

+Use 'client' to interact with Accumulo
+
+| Welcome to JShell -- Version 11.0.10
+| For an introduction type: /help intro
+
+jshell>
+</code></pre></div></div>
+
+<p>If <code class="language-plaintext
highlighter-rouge">accumulo-client.properties</code> is not found, an <a
href="https://www.javadoc.io/doc/org.apache.accumulo/accumulo-core/latest/org/apache/accumulo/core/client/AccumuloClient.html";>AccumuloClient</a>
will not
+auto-generate and will produce the following result below:</p>

+<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre
class="highlight"><code>Preparing JShell for Apache Accumulo

+'accumulo-client.properties' was not found on the classpath

+</code></pre></div></div>
+
+<p>2) Providing JShell with an Accumulo task</p>
+
+<pre><code class="language-Java"> // Create a table called "GothamPD".
+ client.tableOperations().create("GothamPD");
+
+ // Create a Mutation object to hold all changes to a row in a table.
+ // Each row has a unique row ID.
+ Mutation mutation = new Mutation("id0001");
+
+ // Create key/value pairs for Batman. Put them in the "hero" family.
+ mutation.put("hero", "alias", "Batman");
+ mutation.put("hero", "name", "Bruce Wayne");
+ mutation.put("hero", "wearsCape?", "true");
+
+ // Create a BatchWriter to the GothamPD table and add your mutation to it.
+ // Try w/ resources will close for us.
+ try (BatchWriter writer = client.createBatchWriter("GothamPD")) {
+ writer.addMutation(mutation);
+ }
+
+ // Read and print all rows of the "GothamPD" table.
+ // Try w/ resources will close for us.
+ try (ScannerBase scan = client.createScanner("GothamPD",
Authorizations.EMPTY)) {
+ System.out.println("Gotham Police Department Persons of Interest:");
+
+ // A Scanner is an extension of java.lang.Iterable so behaves just like
one.
+ scan.forEach((k, v) -> System.out.printf("Key : %-50s Value : %s\n", k,
v));
+ }
+</code></pre>
+
+<p><strong>Note:</strong> The fully-qualified class name for Accumulo Scanner
or
+<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.core.client.Scanner</code> needs to be
used due to conflicting issues with
+Java’s built-in java.util.Scanner. However, to shorten the Accumulo Scanner’s
declaration, assign
+scan to <code class="language-plaintext highlighter-rouge">ScannerBase</code>
type instead.</p>
+
+<p>3) Executing the Accumulo task above outputs:</p>
+
+<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre
class="highlight"><code>mutation ==> org.apache.accumulo.core.data.Mutation@1
+Gotham Police Department Persons of Interest:
+Key : id0001 hero:alias [] 1618926204602 false Value : Batman
+Key : id0001 hero:name [] 1618926204602 false Value : Bruce Wayne
+Key : id0001 hero:wearsCape? [] 1618926204602 false Value : true

- <title>Top 10 Reasons to Upgrade</title>
- <description><p>Accumulo 2.0 has been in development for quite
some time now and is packed with new features, bug
-fixes, performance improvements and redesigned components. All of these
changes bring challenges
-when upgrading your production cluster so you may be wondering… why should I
upgrade?</p>
-
-<p>My top 10 reasons to upgrade. For all changes see the <a

-
-<h3 id="summaries">Summaries</h3>
-
-<p>This feature allows detailed stats about Tables to be written
directly into Accumulo files (R-Files).
-Summaries can be used to make precise decisions about your data. Once
configured, summaries become a
-part of your Tables, so they won’t impact ingest or query performance of your
cluster.</p>
-
-<p>Here are some example use cases:</p>
-
-<ul>
- <li>A compaction could automatically run if deletes compose more than
25% of the data</li>
- <li>An admin could optimize compactions by configuring specific age
off of data</li>
- <li>An admin could analyze R-File summaries for better performance
tuning of a cluster</li>
-</ul>
-
-<p>For more info check out the <a
href="/docs/2.x//development/summaries">summary docs for
2.0</a></p>
-
-<h3 id="new-bulk-import">New Bulk Import</h3>
-
-<p>Bulk Ingest was completely redone for 2.0. Previously, Bulk Ingest
relied on expensive inspections of
-R-Files across multiple Tablet Servers. With enough data, an old Bulk Ingest
operation could easily
-hold up simpler Table operations and critical compactions of files.</p>
-
-<p>The new Bulk Ingest gives the user control over the R-File
inspection, allows for offline bulk
-ingesting and provides performance <a
href="/release/accumulo-2.0.0/#new-bulk-import-api">improvements</a>.</p>
-
-<h2 id="simplified-scripts-and-config">Simplified Scripts and
Config</h2>
-
-<p>Many improvements were done to the scripts and configuration. See
Mike’s description of the <a
href="/blog/2016/11/16/simpler-scripts-and-config.html">improvements.</a></p>
-
-<h2 id="new-monitor">New Monitor</h2>
-
-<p>The Monitor has been re-written using REST, Javascript and more
modern Web Tech. It is faster,
-cleaner and more maintainable than the previous version. Here is a screen
shot:</p>
-
-<p><img src="/images/accumulo-monitor-1.png"
width="50%" /></p>
-
-<h2 id="new-apis">New APIs</h2>
-
-<p>Connecting to Accumulo is now easier with a single point of entry for
clients. It can now be done with
-a fluent API, 2 imports and using minimal code:</p>
-

class="s">"newTable"</span><span

- <span class="o">}</span>
-</code></pre></div></div>
-
-<p>As you can see the client is also closable, which gives developers
more control over resources.

-
-<h2 id="table-creation-options">Table creation
options</h2>
-
-<p>Tables can now be created with splits, which is much faster than
creating a
-table and then adding splits. Tables can also be created in an offline state
-now. The new bulk import API supports offline tables. This enables the
-following method of getting a lot of data into a new table very
quickly.</p>
-
-<ul>
- <li>Create offline table with splits</li>
- <li>Bulk import into new offline table</li>
- <li>Bring table online</li>
-</ul>
-
-<p>See the javadoc for <a
href="https://static.javadoc.io/org.apache.accumulo/accumulo-core/2.0.1/org/apache/accumulo/core/client/admin/NewTableConfiguration.html">NewTableConfiguration</a>
and search for methods introduced in 2.0.0 for more information.</p>
-
-<h2 id="search-documentation">Search Documentation</h2>
-
-<p>New ability to quickly search documentation on the website. The user
manual was completely redone
-for 2.0. Check it out <a
href="/docs/2.x//getting-started/quickstart">here</a>. Users
can now quickly <a href="/search/">search</a> the website
across all 2.x documentation.</p>
-
-<h2 id="new-crypto">New Crypto</h2>
-
-<p>On disk encryption was redone to be more secure and flexible. For an
in depth description of how Accumulo
-does on disk encryption, see the <a
href="/docs/2.x//security/on-disk-encryption">user
manual</a>. NOTE: This is currently an experimental feature.
-An experimental feature is considered a work in progress or incomplete and
could change.</p>
-
-<h2 id="zstandard-compression">Zstandard compression</h2>
-
-<p>Support for Zstandard compression was added in 2.0. It has been
measured to perform better than
-gzip (better compression ratio and speed) and snappy (better compression
ratio). Checkout Facebook’s <a
href="https://facebook.github.io/zstd/">github</a> for
Zstandard and
-the <a
href="/docs/2.x//configuration/server-properties">table.file.compress.type</a>
property for configuring Accumulo.</p>
-
-<h2 id="new-scan-executors">New Scan Executors</h2>
-
-<p>Users now have more control over scans with the new scan executors.
Tables can be configured to utilize these
-powerful new mechanisms using just a few properties, giving user control over
things like scan prioritization and
-better cluster resource utilization.</p>
-
-<p>For example, a cluster has a bunch of long running scans and one
really fast scan. The long running scans will eat up
-a majority of the server resources causing the one really fast scan to be
delayed. Scan executors allow an admin
-to configure the cluster in a way that allows the one fast scan to be
prioritized and not have to wait.</p>
-
-<p>Checkout some examples in the <a
href="/docs/2.x//administration/scan-executors">user
guide</a>.</p>
