Subject Re: Regions loading too fast
Date Fri, 24 Sep 2010 23:16:51 GMT
Still having a problem:

2010-09-24 16:15:02,572 ERROR
org.apache.hadoop.hbase.regionserver.HRegionServer: Error opening
img695,p1908101232.jpg,1285288492084.d451f05024b42f71a115951c62cdcccf.
java.io.EOFException

I changed the value to '1', and restarted the regionserver... Note
that my hdfs is not having a problem.
