Subject [jira] [Updated] (HBASE-12596) bulkload needs to follow locality
Date Fri, 03 Jul 2015 03:00:06 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12596?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Victor Xu updated HBASE-12596:
------------------------------
    Description: 
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 disabled by default, and we could use 'hbase.bulkload.locality.sensitive.enabled'
to enable it.
