Subject [jira] [Updated] (ACCUMULO-3293) bin\winutils.exe not found when running MiniAccumuloCluster under Windows
Date Tue, 04 Nov 2014 12:36:34 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-3293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Johannes Bauer updated ACCUMULO-3293:
-------------------------------------
    Description: 
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 
{{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)}}
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\MiniAccumuloClusterImpl.java}}:

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!
