Subject UnsatisfiedLinkError installing Hadoop on Windows
Date Wed, 03 Jun 2015 16:18:26 GMT
Hello -

I am trying to work through the documentation at http://wiki.apache.org/hadoop/Hadoop2OnWindows
to get a basic single node instance of Hadoop running on Windows.  I am on step 3.5, where
I am executing the line "%HADOOP_PREFIX%\bin\hdfs dfs -put myfile.txt /", and I get the following
stack trace:

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.util.NativeCrc32.nativeComputeChunkedSumsByteArray(II[BI[BIILjava/lang/String;JZ)V
