Hi, I'm trying to run the hdfs_test that comes alongside the C API of HDFS. So far I tried both versions 0.20.3 and 0.21.0, and I'm getting two different errors. In 0.20.3, I'm getting this:
[/$HADOOP_HOME/src/c++/libhdfs] ./hdfs_test ./hdfs_test: symbol lookup error: /$HADOOP_HOME/build/c++/Linux-i386-32/lib/libhdfs.so.0: undefined symbol: JNI_GetCreatedJavaVMs In 0.21.0, I'm getting: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.apache.hadoop.conf.Configuration.<clinit>(Configuration.java:153) Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) ... 1 more Can't construct instance of class org.apache.hadoop.conf.Configuration Oops!
