"C" APIs for HBase.

  mvn install -DskipTests

This will build the tarball containing the headers, shared library and the jars in the target directory with the following structure.

+---bin
+---conf
+---include
|   \---hbase
+---lib
|   \---native
\---src
    \---examples
        \---async

The headers can be found under include folder while the shared library to link against is under lib/native.

libHBase uses GTest as the test framework for unit/integration tests. During the build process, it automatically downloads and build the GTest. You will need to have cmake installed on the build machine to build the GTest framwork.

Runnig the unit tests currently requires you to set LIBHBASE_ZK_QUORUM to a valid HBase Zookeeper quorum. The default is "localhost:2181". This can be either set as an environment variable or in this configuration file.

LIBHBASE_ZK_QUORUM="<zk_host>:<zk_port>,..." mvn integration-test

For examples on how to use the APIs, please take a look at this sample source.

As the library uses JNI, you will need to have both libhbase and libjvm shared libraries in your application's library search path. The jars required for the library can be specified through either of the environment variables CLASSPATH or HBASE_LIB_DIR. Custom JVM options, for example -Xmx, etc can be specified using the environment variable LIBHBASE_OPTS.

A performance test is included with the library which currently support sequential/random gets and puts. You can run the tests using this shell script.
