Hello Mikael, I am fairly new to HBase, so correct me if I am wrong - it seems to me that the WAL and the HFile store impose distinctly different requirements upon the underlying storage. The WAL really wants Posix semantics (append, flush, etc.) in a distributed filesystem whereas the HFile store wants more of an object store with full object reads and writes.
Adding this configuration option, or better yet, making the WAL fully pluggable as described in https://issues.apache.org/jira/browse/HBASE-4529, opens up a lot more storage architectures to HBase. Thanks, Jagane ________________________________________ From: Mikael Sitruk [[email protected]] Sent: Wednesday, December 28, 2011 7:29 AM To: [email protected] Subject: Re: Writing the WAL to a different filesystem from the HFiles What is the advantage of such configuration?
