hadoop-unable to load Native-hadoop library for your platform

Brief introduction

When running Hadoop or spark (call HDFs, etc.), the error "Unable to load Native-hadoop library for your platform" is not actually loading the local library

Solutions

1. Whether the environment variable is set (set but not yet try the second step)

Export hadoop_common_lib_native_dir= $HADOOP _home/lib/native
Export hadoop_opts= "-djava.library.path= $HADOOP _home/lib/native"

2. If the default libhadoop.so.1.0.0 (lib/native) is 32 bits, and the machine is 64 bits, you need to compile Hadoop and replace the files in Lib

Compiling installation options

MVN Clean package-pdist-dtar-dmaven.javadoc.skip=true-dskiptests-fail-at-end-pnative

If prompted to ' Libprotoc 2.5.0

9 sudo ldconfig

If it is in the Ubuntu14.04, prompt libtool error, then use/usr/bin/libtool to replace the Libtool in the file

Compiled files

Set the logging level for Hadoop

Export Hadoop_root_logger=debug,console
