[ https://issues.apache.org/jira/browse/HBASE-6236?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aditya Kishore updated HBASE-6236: ---------------------------------- Attachment: HBASE-6236_trunk.patch Change Summary (consolidated): ------------------------------- 1. Changed the default sideline folder to "/hbase/.hbck/hbase-xxxxxxxxx" where xxxxxxxxx is System.currentTimeMillis(). 2. Added a command line option "-sidelineDir" to override this default. 3. Added ".hbck" to the list of Non-user table dir so that it is not treated as a user table folder. 4. Fixed the potential NPE in argument parsing code. Thank you all for your valuable time spent reviewing my submission :) > Offline meta repair fails if the HBase base mount point is on a different > cluster/volume than its parent in a ViewFS or similar FS > ---------------------------------------------------------------------------------------------------------------------------------- > > 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, > HBASE-6236_trunk.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' -- This message is automatically generated by JIRA.
