> Key: HBASE-6236
> URL: https://issues.apache.org/jira/browse/HBASE-6236
> Project: HBase
> Issue Type: Bug
> Components: hbck
> Reporter: Aditya Kishore
> Assignee: Aditya Kishore
> Fix For: 0.96.0, 0.94.1
>
> Attachments: 6236_trunk.patch, HBASE-6236_94.patch,

> While building the .META. and \-ROOT\- from FS data alone (HBASE-4377), hbck
> tries to move the existing .META. and \-ROOT\- directories to a backup folder.
> This backup folder is created at the same level as the base HBase folder
> (e.g. /hbase-xxxxxx if the base HBase folder is '/hbase').
> In a federated HDFS like ViewFS and other similar FS implementations, it is
> not possible to rename files/directories across namespace volumes (ViewFS
> guide section 3.5) and as a result hbck crashes.
> A solution to this problem is to create the backup directory under the folder
> where HBase base folder has been mounted. This ensures that source and
> destination of rename operation are on the same namespace volume.
> Patch for 0.94 and trunk is attached for review. The patch modifies the
> location of the backup directory from '/hbase-xxxxxxx' to
> '/hbase/.hbcktmp-xxxxxxx'
