[jira] [Commented] (HBASE-3696) No durability when running with
LocalFileSystem
[ https://issues.apache.org/jira/browse/HBASE-3696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13576167#comment-13576167 ]
Ian Varley commented on HBASE-3696:
-----------------------------------
This confused me a bit today while trying to debug HBase replication running locally; you have to roll the HLog in order for ReplicationSource to pick up and replicate your edits. +1 to a fix (but, no idea what that'd be; an implementation of sync() for LocalFileSystem?)

> LocalFileSystem in Hadoop doesn't currently implement sync(), so when we're running in that case, we don't have any durability. This isn't a huge deal since it isn't a realistic deployment scenario, but it's probably worth documenting. It caused some confusion for a user when a table disappeared after killing a standalone instance that was hosting its data in the local FS.
