for how to up the limit. Also, as of 0.18.x hadoop, datanodes have an
upper-bound
on the number of threads they will support
(<code>dfs.datanode.max.xcievers</code>).

your
- hadoop cluster.
+ Default is 256. Up this limit on your hadoop cluster.
<li>The clocks on cluster members should be in basic alignments. Some
skew is tolerable but
wild skew can generate odd behaviors. Run <a

on your cluster, or an equivalent.</li>
+ <li>HBase servers put up 10 listeners for incoming connections by
default. Up this

hbase.regionserver.handler.count

unusable"</i></a>. This patch will help with the ever-popular, "No live nodes
contain current block".
