Subject [jira] Commented: (HBASE-2681) Graceful fallback to NONE when the native compression algo is not found
Date Mon, 07 Jun 2010 20:36:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12876406#action_12876406
] 

ryan rawson commented on HBASE-2681:
------------------------------------

During a flush/hfile write it is easy to fall back to "NONE", but when you try to read a HFile
(which was written with a specific codec) and that codec fails to load then there is no good
graceful failure while also returning data.

> stack's word: "Fellas have complained about the way broke lzo manifests itself. HBase
will actually take on writes. Its only when it goes to flush that it drops the edits and in
a way that is essentially hidden to the client - exceptions are thrown in the regionserver
log. So, i'd say, make another issue if you don't mind but its not for you to fix, not unless
you are inclined. It'd be about better user experience around choosing a compression that
is not supported or not properly installed."
