I am trying out hbase on my local machine. I ran out of file handles while
loading Wikipedia pages into a table as a test:
2009-07-13 18:59:20,223 FATAL
org.apache.hadoop.hbase.regionserver.MemcacheFlusher: Replay of hlog

I could not find any documentation on how to manually replay the hlog.
It doesn't seem to have done automatically so when I shutdown and
restarted the server.
Getting a row count of the table I had been loading data into gave me no
results. But I have 31GB of data in my hbase data directory, many of which
are oldlogfile.log.
How do I recover the data stored there? Why is the recovery not automatic?
Thanks,
