Windows上的Hadoop錯誤：java.lang.UnsatisfiedLinkError

我是Hadoop的新手，試圖執行我的第一個wordcount的mapreduce作業。但是，每當我試圖做到這一點，我得到下面的錯誤：Windows上的Hadoop錯誤：java.lang.UnsatisfiedLinkError

此外，當我做

的Hadoop checknative -a

它顯示我以下細節：

Native library checking: 
hadoop: true C:\hadoop-2.6.1\bin\hadoop.dll 
zlib: false 
snappy: false 
lz4:  true revision:43 
bzip2: false 
openssl: false org.apache.hadoop.util.NativeCodeLoader.buildSupportsOpenssl()Z 
winutils: true C:\hadoop-2.6.1\bin\winutils.exe 
15/10/19 15:18:24 INFO util.ExitUtil: Exiting with status 1

有沒有什麼辦法可以解決這個問題？
