---------------------------------
Summary: bulkload needs to follow locality
Key: HBASE-12596
URL: https://issues.apache.org/jira/browse/HBASE-12596
Project: HBase
Issue Type: Improvement
Components: HFile, regionserver
Affects Versions: 0.98.8
Environment: hadoop-2.3.0, hbase-0.98.8, jdk1.7
Reporter: Victor Xu
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().
