Andrew Purtell resolved HBASE-1108.
-----------------------------------
Resolution: Not a Problem
Not needed after HBCK
> Redundant meta tables
> ---------------------
>
> Key: HBASE-1108
> URL: https://issues.apache.org/jira/browse/HBASE-1108
> Project: HBase
> Issue Type: Sub-task
> Reporter: Andrew Purtell
>
> If the data file for -ROOT- or .META. is damaged, a HBase installation is
> rendered inoperative. Manual recovery through writing a new -ROOT- by hand is
> relatively simple (I think) but it's not simple and maybe not even possible
> to recreate a .META. containing thousands of regions. During one experiment I
> lost the entire .META. data file due to DFS errors during compaction. This
> can be avoided by utilizing multiple backing data files for -ROOT- and .META.
> synchronized in a manner that avoids total data loss should the filesystem
> become degraded.
