Johannes Bauer reopened ACCUMULO-3293:
--------------------------------------

As Rich reported the same bug, I'll repen the issue, even though I don't have the problem
any more at the moment. 

> bin\winutils.exe not found when running MiniAccumuloCluster under Windows

>                 Key: ACCUMULO-3293
>                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3293
>             Project: Accumulo
>          Issue Type: Bug
>          Components: mini
>         Environment: MS Windows
>            Reporter: Johannes Bauer

> When running JUnit-Tests on Windows with the MiniAccumuloCluster, the file {{bin\winutils.exe}}
is needed, which is searched in the path, given by the system variable {{HADOOP_HOME}}. This
worked fine with the MiniAccumuloCluster 1.4.4.
> When I try the same with Accumulo 1.6, I get the error 
> {code}
> 14/10/24 16:57:40 ERROR util.Shell: Failed to locate the winutils binary in the hadoop
binary path
> java.io.IOException: Could not locate executable C:\Users\jsbaue\AppData\Local\Temp\1414162594270-0\bin\winutils.exe
in the Hadoop binaries.
> 	at org.apache.hadoop.util.Shell.getQualifiedBinPath(Shell.java:318)
> 	at org.apache.hadoop.util.Shell.getWinUtilsPath(Shell.java:333)
> 	at org.apache.hadoop.util.Shell.<clinit>(Shell.java:326)
> 	at org.apache.hadoop.util.StringUtils.<clinit>(StringUtils.java:76)
> {code}
> which basically says, that {{bin\winutils.exe}} is now searched in the temporary path,
given to the MiniAccumuloCluster. When I try to put the file {{bin\winutils.exe}} in that
path, I get an error, saying that the path has to be empty. 
> I fixed this problem by changing {{accumulo\minicluster\src\main\java\org\apache\accumulo\minicluster\impl\MiniAccumuloClusterImpl.java}}:
> I exchanged Line 309-310:
> {code}
>     // hadoop-2.2 puts error messages in the logs if this is not set
>     builder.environment().put("HADOOP_HOME", config.getDir().getAbsolutePath());
> {code}
> with the following lines: 
> {code}
>     env = System.getProperty("hadoop.home.dir");
>     if(env == null) 
>         env = System.getenv("HADOOP_HOME");
>     // hadoop-2.2 puts error messages in the logs if this is not set
>     if(env == null)
>         env = config.getDir().getAbsolutePath();
>     builder.environment().put("HADOOP_HOME", env);
> {code}
> This fixes the bug on Windows. I did no checks on Linux. 
> Could you check, if you chould change this in the next version of the MiniAccumuloCluster
or help me with an other solution? Thanks!
