-libhdfs is a JNI based C API for Hadoop's Distributed File System (HDFS).
-It provides C APIs to a subset of the HDFS APIs to manipulate HDFS files and
-the filesystem. libhdfs is part of the Hadoop distribution and comes 
-pre-compiled in ${HADOOP_PREFIX}/libhdfs/libhdfs.so .

-See the Makefile for hdfs_test.c in the libhdfs source directory (${HADOOP_PREFIX}/src/c++/libhdfs/Makefile)

-<title>Common Problems</title>
-<p>
-The most common problem is the CLASSPATH is not set properly when calling a program that
uses libhdfs. 
-Make sure you set it to all the Hadoop jars needed to run Hadoop itself. Currently, there
is no way to 
-programmatically generate the classpath, but a good bet is to include all the jar files in
${HADOOP_PREFIX} 
-and ${HADOOP_PREFIX}/lib as well as the right configuration directory containing hdfs-site.xml

-<title>Thread Safe</title>
-<p>libdhfs is thread safe.</p>
-<ul>
-<li>Concurrency and Hadoop FS "handles" 
-<br />The Hadoop FS implementation includes a FS handle cache which caches based on
the URI of the 
-namenode along with the user connecting. So, all calls to hdfsConnect will return the same
handle but 
-calls to hdfsConnectAsUser with different users will return different handles.  But, since
HDFS client 
-handles are completely thread safe, this has no bearing on concurrency. 
-</li>
-<li>Concurrency and libhdfs/JNI 
-<br />The libhdfs calls to JNI should always be creating thread local storage, so (in
theory), libhdfs 
-should be as thread safe as the underlying calls to the Hadoop FS.
