Subject [jira] [Commented] (HBASE-11134) Add a -list-snapshots option to SnapshotInfo
Date Sat, 10 May 2014 21:59:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993951#comment-13993951

Matteo Bertozzi commented on HBASE-11134:

{quote}Binding these vars to FSUtils so they can be picked up later seems strange – can't
this be made more explicit (e.g. when remote is specified we set some vars, if not we load
defaults, and then make the static that lists use those vars){quote}
This isn't specific of list snapshot. this is a quick way to specify a different location.
currently you have to do -Dhbase.root=REMOTE_DIR -Dfs.defaultFS=REMOTE_DIR
I don't want pass around locations all around the code because you may want a different root-dir
than the one that you have in the conf file. It is just an helper. getSnapshotList() is doing
just what is supposed to do, from the configuration that you have specified list the snapshots.
