[jira] [Commented] (HBASE-14049) SnapshotHFileCleaner should optionally clean up after failed snapshots

["Andrew Purtell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-14049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14620981#comment-14620981 ] 

Andrew Purtell commented on HBASE-14049:
----------------------------------------

After a HDFS level blip during snapshotting we typically see detritus missing .snapshotinfo, or having one that is corrupt, leading to InvalidProtocolBufferException upon read attempt. Today SnapshotHFileCleaner only warns and moves on:

{noformat]
2015-07-02 16:29:49,490 ERROR [archivedHFileCleaner] snapshot.SnapshotHFileCleaner -
Exception while checking if files were valid, keeping them just in case.
...
{noformat}

leading to a lot of log noise until the problem is manually addressed.

> SnapshotHFileCleaner should optionally clean up after failed snapshots rather than just complain. Add a configuration option that, if set to true (defaulting to false), instructs SnapshotHFileCleaner to recursively remove failed snapshot temporary directories.
