-BookKeeper as a Shared storage (EXPERIMENTAL)
----------------------------------------------
-
-One option for shared storage for the NameNode is BookKeeper. BookKeeper achieves high availability
and strong durability guarantees by replicating edit log entries across multiple storage nodes.
The edit log can be striped across the storage nodes for high performance. Fencing is supported
in the protocol, i.e, BookKeeper will not allow two writers to write the single edit log.
-
-The meta data for BookKeeper is stored in ZooKeeper. In current HA architecture, a Zookeeper
cluster is required for ZKFC. The same cluster can be for BookKeeper metadata.
-
-For more details on building a BookKeeper cluster, please refer to the [BookKeeper documentation](http://zookeeper.apache.org/bookkeeper/docs/trunk/bookkeeperConfig.html
)
-
-The BookKeeperJournalManager is an implementation of the HDFS JournalManager interface, which
allows custom write ahead logging implementations to be plugged into the HDFS NameNode.
-
-*   **BookKeeper Journal Manager**
-
-    To use BookKeeperJournalManager, add the following to hdfs-site.xml.
-
-            <property>
-              <name>dfs.namenode.shared.edits.dir</name>
-              <value>bookkeeper://zk1:2181;zk2:2181;zk3:2181/hdfsjournal</value>
-            </property>
-
-            <property>
-              <name>dfs.namenode.edits.journal-plugin.bookkeeper</name>
-              <value>org.apache.hadoop.contrib.bkjournal.BookKeeperJournalManager</value>
-            </property>
-
-    The URI format for bookkeeper is `bookkeeper://[zkEnsemble]/[rootZnode] [zookkeeper ensemble]`
-    is a list of semi-colon separated, zookeeper host:port
-    pairs. In the example above there are 3 servers, in the ensemble,
-    zk1, zk2 & zk3, each one listening on port 2181.
-
-    `[root znode]` is the path of the zookeeper znode, under which the edit log
-    information will be stored.
-
-    The class specified for the journal-plugin must be available in the NameNode's
-    classpath. We explain how to generate a jar file with the journal manager and
-    its dependencies, and how to put it into the classpath below.
-
-*   **More configuration options**
-
-    *   **dfs.namenode.bookkeeperjournal.output-buffer-size** -
-        Number of bytes a bookkeeper journal stream will buffer before
-        forcing a flush. Default is 1024.
-
-                   <property>
-                     <name>dfs.namenode.bookkeeperjournal.output-buffer-size</name>
-                     <value>1024</value>
-                   </property>
-
-    *   **dfs.namenode.bookkeeperjournal.ensemble-size** -
-    Number of bookkeeper servers in edit log ensembles. This
-    is the number of bookkeeper servers which need to be available
-    for the edit log to be writable. Default is 3.
-
-                   <property>
-                     <name>dfs.namenode.bookkeeperjournal.ensemble-size</name>
-                     <value>3</value>
-                   </property>
-
-    * **dfs.namenode.bookkeeperjournal.quorum-size** -
-    Number of bookkeeper servers in the write quorum. This is the
-    number of bookkeeper servers which must have acknowledged the
-    write of an entry before it is considered written. Default is 2.
-
-                   <property>
-                     <name>dfs.namenode.bookkeeperjournal.quorum-size</name>
-                     <value>2</value>
-                   </property>
-
-    * **dfs.namenode.bookkeeperjournal.digestPw** -
-    Password to use when creating edit log segments.
-
-                   <property>
-                    <name>dfs.namenode.bookkeeperjournal.digestPw</name>
-                    <value>myPassword</value>
-                   </property>
-
-    * **dfs.namenode.bookkeeperjournal.zk.session.timeout** -
-    Session timeout for Zookeeper client from BookKeeper Journal Manager.
-    Hadoop recommends that this value should be less than the ZKFC
-    session timeout value. Default value is 3000.
-
-                   <property>
-                     <name>dfs.namenode.bookkeeperjournal.zk.session.timeout</name>
-                     <value>3000</value>
-                   </property>
-
-*   **Building BookKeeper Journal Manager plugin jar**
-
-    To generate the distribution packages for BK journal, do the following.
-
-    $ mvn clean package -Pdist
-
-    This will generate a jar with the BookKeeperJournalManager,
-    hadoop-hdfs/src/contrib/bkjournal/target/hadoop-hdfs-bkjournal-*VERSION*.jar
-
-    Note that the -Pdist part of the build command is important, this would
-    copy the dependent bookkeeper-server jar under
-    hadoop-hdfs/src/contrib/bkjournal/target/lib.
-
-*   **Putting the BookKeeperJournalManager in the NameNode classpath**
-
-    To run a HDFS namenode using BookKeeper as a backend, copy the bkjournal and
-    bookkeeper-server jar, mentioned above, into the lib directory of hdfs. In the
-    standard distribution of HDFS, this is at $HADOOP\_HDFS\_HOME/share/hadoop/hdfs/lib/
-
-    cp hadoop-hdfs/src/contrib/bkjournal/target/hadoop-hdfs-bkjournal-*VERSION*.jar $HADOOP\_HDFS\_HOME/share/hadoop/hdfs/lib/
-
-*   **Current limitations**
-
-    1) Security in BookKeeper. BookKeeper does not support SASL nor SSL for
-    connections between the NameNode and BookKeeper storage nodes.
