Subject [jira] [Updated] (HBASE-7294) Check for snapshot file cleaners on start
Date Sat, 29 Dec 2012 10:48:13 GMT

     [ https://issues.apache.org/jira/browse/HBASE-7294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matteo Bertozzi updated HBASE-7294:
-----------------------------------

    Attachment: HBASE-7294-v7.patch

TestInfoServers got an exception generated from the snapshots not enabled.
TestSnapshotFromMaster had two problems:
The TTL on by default after the new snapshot.enabled property introduced (so files are not
removed immediately after the first cleaner call)
and enableTable() trigger a compaction (async) and sometimes (on jenkins) is slow and the
files are still there, and one of the assert fail.

> Snapshots currently use the SnaphotHfileCleaner and SnapshotHLogCleaner to ensure that
any hfiles or hlogs (respectively) that are currently part of a snapshot are not removed from
their respective archive directories (.archive and .oldlogs).
> From Matteo Bertozzi:
> {quote}
> currently the snapshot cleaner is not in hbase-default.xml
> and there's no warning/exception on snapshot/restore operation, if not enabled.
> even if we add the cleaner to the hbase-default.xml how do we ensure that the user doesn't
remove it?
> Do we want to hardcode the cleaner at master startup?
> Do we want to add a check in snapshot/restore that throws an exception if the cleaner
is not enabled?
