Summary: Verify that a snapshot is not corrupted before restoring
it
Key: HBASE-10111
URL: https://issues.apache.org/jira/browse/HBASE-10111
Project: HBase
Issue Type: Bug
Components: snapshots
Affects Versions: 0.94.14, 0.96.0, 0.98.0
Reporter: Matteo Bertozzi
Assignee: Matteo Bertozzi
Priority: Minor
Fix For: 0.98.0, 0.96.1
Attachments: HBASE-10111-v0.patch
To avoid assigning/opening regions with missing files, verify that the snapshot
is not corrupted before restoring/cloning it.
In 96 a corrupted file in a region is "not a problem" since the assignment will
give up after awhile.
In 94 having a corrupted file in a region means looping forever, on "enable",
until manual intervention. (Easy way to test this is create a table, disable
it, add a corrupted reference file and enable the table to start looping: you
can use echo "foo" >
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
