Hbase Thrift Client Examples
|
||||||
|
============================
|
||||||
|
|
||||||
|
Included in this directory are sample clients of the HBase ThriftServer. They
|
||||||
|
all perform the same actions but are implemented in C++, Java, and Ruby
|
||||||
|
respectively.
|
||||||
|
|
||||||
|
To run/compile this clients, you will first need to install the thrift package
|
||||||
|
(from http://developers.facebook.com/thrift/) and then run thrift to generate
|
||||||
|
the language files:
|
||||||
|
|
||||||
|
thrift -cpp -java -rb \
|
||||||
|
../../../src/java/org/apache/hadoop/hbase/thrift/Hbase.thrift

Provides an HBase <a href="http://developers.facebook.com/thrift/">Thrift</a>
|
||||||
|
service.
|
||||||
|
|
||||||
|
This directory contains a Thrift interface definition file for an Hbase RPC
|
||||||
|
service and a Java server implementation.
|
||||||
|
|
||||||
|
<h2><a name="whatisthrift">What is Thrift?</a></h2>
|
||||||
|
|
||||||
|
<p>"Thrift is a software framework for scalable cross-language services
|
||||||
|
development. It combines a powerful software stack with a code generation
|
||||||
|
engine to build services that work efficiently and seamlessly between C++,
|
||||||
|
Java, Python, PHP, and Ruby. Thrift was developed at Facebook, and we are now
|
||||||
|
releasing it as open source." For additional information, see
|
||||||
|
http://developers.facebook.com/thrift/. Facebook has announced their intent
|
||||||
|
to migrate Thrift into Apache Incubator.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2><a name="description">Description</a></h2>
|
||||||
|
|
||||||
|
<p>The <a href="generated/Hbase.Iface.html">Hbase API</a> is defined in the
|
||||||
|
file Hbase.thrift. A server-side implementation of the API is in {@link
|
||||||
|
org.apache.hadoop.hbase.thrift.ThriftServer}. The generated interfaces,
|
||||||
|
types, and RPC utility files are checked into SVN under the {@link
|
||||||
|
org.apache.hadoop.hbase.thrift.generated} directory.
|
||||||
|
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>The files were generated by running the commands:
|
||||||
|
<pre>
|
||||||
|
thrift -strict -java Hbase.thrift
|
||||||
|
mv gen-java/org/apache/hadoop/hbase/thrift/generated .
|
||||||
|
rm -rf gen-java
|
||||||
|
</pre>
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>The 'thrift' binary is the Thrift compiler, and it is distributed as a part
|
||||||
|
of
|
||||||
|
the Thrift package. Additionally, specific language runtime libraries are a
|
||||||
|
part of the Thrift package. A version of the Java runtime is checked into SVN
|
||||||
|
under the hbase/lib directory.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>The version of Thrift used to generate the Java files is revision 746 from
|
||||||
|
the <a href="http://svn.facebook.com/svnroot/thrift/">SVN repository</a>.</p>
|
||||||
|
|
||||||
|
<p>The ThriftServer is run like:
|
||||||
|
<pre>
|
||||||
|
|
||||||
|
./bin/hbase thrift [-h|--help] [-p|--port PORT]
|
||||||
|
</pre>
|
||||||
|
The default port is 9090.
