Subject [jira] [Commented] (HBASE-8352) Rename '.snapshot' directory
Date Tue, 16 Apr 2013 22:01:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13633451#comment-13633451
] 

Ted Yu commented on HBASE-8352:
-------------------------------

I thought about that. getCompletedSnapshots() references ".snapshot" (old name).
I can expose the following constant and reference it from getCompletedSnapshots():
{code}
  /* Name of old snapshot directory. See HBASE-8352 for details on why it needs to be renamed
*/
  public static final String OLD_SNAPSHOT_DIR_NAME = ".snapshot";
{code}
                
> Rename '.snapshot' directory

> Testing HBase Snapshot on top of Hadoop's Snapshot branch (http://svn.apache.org/viewvc/hadoop/common/branches/HDFS-2802/),
we found that both features used '.snapshot' directory to store metadata.
> HDFS (built from HDFS-2802 branch) doesn't allow paths with .snapshot as a component
> From discussion on dev@hbase.apache.org, (see http://search-hadoop.com/m/kY6C3cXMs51),
consensus was to rename '.snapshot' directory in HBase so that both features can co-exist
smoothly.
