[hbase] restructure how HBase lays out files in the file system
---------------------------------------------------------------
Key: HADOOP-2478
URL: https://issues.apache.org/jira/browse/HADOOP-2478
Project: Hadoop
Issue Type: Improvement
Components: contrib/hbase
Affects Versions: 0.16.0
Reporter: Jim Kellerman
Assignee: Jim Kellerman
Fix For: 0.16.0
Currently HBase has a pretty flat directory structure. For example:
{code}
/hbase/hregion_70236052/info
/hbase/hregion_70236052/info/info/4328260619704027575
/hbase/hregion_70236052/info/mapfiles/4328260619704027575
/hbase/hregion_70236052/info/mapfiles/4328260619704027575/data
/hbase/hregion_70236052/info/mapfiles/4328260619704027575/index
{code}
All the region directories are under the root directory, and with encoded
region names, it is impossible to determine what table a region belongs to.
This should be restructured to:
{code}
/root-directory/table-name/encoded-region-name/column-family/{info,mapfiles}
{code}
It will be necessary to provide a migration script from current trunk to the
new structure.
