Hudson commented on HBASE-14302: -------------------------------- FAILURE: Integrated in HBase-0.98 #1100 (See [https://builds.apache.org/job/HBase-0.98/1100/]) HBASE-14302 TableSnapshotInputFormat should not create back references when restoring snapshot (enis: rev 1b7d84aa41bdfd7679fd910617eb85a0efd48588) * hbase-server/src/main/java/org/apache/hadoop/hbase/snapshot/RestoreSnapshotHelper.java * hbase-server/src/test/java/org/apache/hadoop/hbase/mapreduce/TestTableSnapshotInputFormat.java * hbase-server/src/main/java/org/apache/hadoop/hbase/io/HFileLink.java * hbase-server/src/test/java/org/apache/hadoop/hbase/mapred/TestTableSnapshotInputFormat.java * hbase-server/src/test/java/org/apache/hadoop/hbase/mapreduce/TableSnapshotInputFormatTestBase.java > TableSnapshotInputFormat should not create back references when restoring > snapshot > ---------------------------------------------------------------------------------- > > Key: HBASE-14302 > URL: https://issues.apache.org/jira/browse/HBASE-14302 > Project: HBase > Issue Type: Bug > Reporter: Enis Soztutar > Assignee: Enis Soztutar > Fix For: 2.0.0, 1.0.2, 1.2.0, 1.3.0, 1.1.3 > > Attachments: hbase-14302_v1.patch > > > TableSnapshotInputFormat restores the snapshot to a temporary directory that > is outside the HBase's root directory so that it can read from the restored > snapshot and also refer to hfiles in the actual root directory. > In restoring the snapshot, we create new hfilelinks in the ephemeral > location. Creating new hfile links also creates "back references" for GC. > These back references are dangling since the restore location is outside the > root dir, and requires a WRITE permission to the root dir (as opposed to just > READ permission) to be able to run the MR-over-snapshot job. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
