#### [Hadoop java.io.IOException: Mkdirs failed to create /some/path](http://stackoverflow.com/questions/10522835/hadoop-java-io-ioexception-mkdirs-failed-to-create-some-path)

Just ran into this problem running mahout from CDH4 in standalone mode in my MacBook Air.

The issue is that a /tmp/hadoop-xxx/xxx/LICENSE file and a /tmp/hadoop-xxx/xxx/license directory are being created on a case-insensitive file system when unjarring the mahout jobs.

I was able to workaround this by deleting META-INF/LICENSE from the jar file like this:

```
zip -d mahout-examples-0.6-cdh4.0.0-job.jar
```

META-INF/LICENSE and then verified it with

```
jar tvf mahout-examples-0.6-cdh4.0.0-job.jar | grep -i license
```
