<para>To view a textualized version of hfile content, you can do use
the
<classname>org.apache.hadoop.hbase.io.hfile.HFile
</classname>
tool. Type the following to see usage:
<code>
$ ${HBASE_HOME}/bin/hbase org.apache.hadoop.hbase.io.hfile.HFile
</code>
For example, to view the content of the file
<filename>hdfs://10.81.47.41:9000/hbase/TEST/1418428042/DSMP/4759508618286845475
</filename>, type the following:
<code>
$ ${HBASE_HOME}/bin/hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f
hdfs://10.81.47.41:9000/hbase/TEST/1418428042/DSMP/4759508618286845475
</code>
If you leave off the option -v to see just a summary on the hfile.
See usage for other things to do with the <classname>HFile</classname> tool.

You can get a textual dump of a WAL file content by doing the following:
<code>bin/hbase org.apache.hadoop.hbase.regionserver.wal.HLog --dump hdfs://example.org:9000/hbase/.logs/example.org,60020,1283516293161/10.10.21.10%3A60020.1283973724012</code>
The return code will be non-zero if issues with the file so you can test wholesomeness of file by
redirecting <varname>STDOUT</varname> to <code>/dev/null</code> and testing the program return.
</para>
<para>Similarily you can force a split of a log file directory by doing
<code>bin/hbase org.apache.hadoop.hbase.regionserver.wal.HLog --split hdfs://example.org:9000/hbase/.logs/example.org,60020,1283516293161/</code>
