Hudson commented on HBASE-6236: ------------------------------- Integrated in HBase-0.94 #272 (See [https://builds.apache.org/job/HBase-0.94/272/]) HBASE-6236 revert upon Jimmy's request. (Revision 1353014) HBASE-6236 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 (Aditya) (Revision 1353012) Result = FAILURE tedyu : Files : * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/util/hbck/OfflineMetaRepair.java tedyu : Files : * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/util/hbck/OfflineMetaRepair.java > 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, 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.
