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>
