<li>This is the current list of patches we recommend you apply to your
running Hadoop cluster:
<ul>
+ <li><a
hef="https://issues.apache.org/jira/browse/HADOOP-4681";>HADOOP-4681/HDFS-127
<i>"DFSClient block read failures cause open DFSInputStream to become
unusable"</i></a>. This patch will help with the ever-popular, "No live nodes
contain current block".
+ The hadoop version bundled with hbase has this patch applied. Its an
HDFS client
+ fix so this should do for usual usage but if your cluster is missing the
patch,
+ and in particular if calling hbase from a mapreduce job, you may run
into this
+ issue. If running with hadoop 0.20.2, it has this patch in place
already.

<a href="https://issues.apache.org/jira/browse/HDFS-630";>HDFS-630:
<em>"In DFSOutputStream.nextBlockOutputStream(), the client can exclude
specific datanodes when locating the next block"</em></a>.
Dead DataNodes take ten minutes to timeout at NameNode.
