-----------------------------------
The failed test above is from HTrace, I ran the test on my local compilation
machine, and it passed. Maybe an environmental problem?

> Normally, we have 2 steps to perform a bulkload: 1. use a job to write HFiles
> to be loaded; 2. Move these HFiles to the right hdfs directory. However, the
> locality could be loss during the first step. Why not just write the HFiles
> directly into the right place? We can do this easily because
> StoreFile.WriterBuilder has the "withFavoredNodes" method, and we just need
> to call it in HFileOutputFormat's getNewWriter().
> This feature is enabled by default, and we could use
> 'hbase.bulkload.locality.sensitive.enabled=false' to disable it.
