Steven Rowe commented on LUCENE-3452:
-------------------------------------

bq. Would a quickfix of prepending or postfixing with the user name work here?

Dawid, as Hoss mentioned (quoted above), it would be even better to 
additionally include (a hash of a filename from) the source directory in which 
the tests are being run, to handle the case of simultaneous test runs by the 
same user.

However, I think an even quick(er)fix would be to just use {{lucene/build/}} as 
the location of the lock, instead of the value of the {{$\{java.io.tmpdir\}}} 
system property.

>          Issue Type: Bug
>          Components: general/test

>            Priority: Minor

> {{LuceneJUnitResultFormatter}} uses a lock to buffer test suites' output, so 
> that when run in parallel, they don't interrupt each other when they are 
> displayed on the console.
> The current implementation uses a fixed directory ({{lucene_junit_lock/}} in 
> {{java.io.tmpdir}} (by default {{/tmp/}} on Unix/Linux systems) as the 
> location of this lock.  This functionality was introduced on SOLR-1835.
> As Shawn Heisey reported on SOLR-2739, some tests fail when run as root, but 
> succeed when run as a non-root user.
