Work on HADOOP-2478 started by Jim Kellerman. > [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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
