> MAPREDUCE-2494 introduced the following findbugs warning in trunk:
> TrackerDistributedCacheManager.java:739, SIC_INNER_SHOULD_BE_STATIC, Priority: Low
> Should org.apache.hadoop.mapreduce.filecache.TrackerDistributedCacheManager$CacheDir
be a _static_ inner class?
> This class is an inner class, but does not use its embedded reference to the object which
created it.  This reference makes the instances of the class larger, and may keep the reference
to the creator object alive longer than necessary.  If possible, the class should be made
static.
