Subject [jira] [Created] (ACCUMULO-3293) bin\winutils.exe not found when running MiniAccumuloCluster under Windows
Date Tue, 04 Nov 2014 12:35:34 GMT
Johannes Bauer created ACCUMULO-3293:

             Summary: bin\winutils.exe not found when running MiniAccumuloCluster under Windows
                 Key: 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 AccumuloMiniCluster 1.4.4.

When I try the same with Accumulo 1.6, I get the error 
{{14/10/24 16:57:40 ERROR util.Shell: Failed to locate the winutils binary in the hadoop binary
{{ 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(}}
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 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\}}:

I exchanged Line 310:

{{    builder.environment().put("HADOOP_HOME", config.getDir().getAbsolutePath());}}

with the following lines: 

{{	env = System.getProperty("hadoop.home.dir");}}
{{	if(env == null) }}
{{	  env = System.getenv("HADOOP_HOME");}}
{{	if(env == null)}}
{{	  env = config.getDir().getAbsolutePath();}}
{{    builder.environment().put("HADOOP_HOME", env);}}

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!
