Subject Re: HDFS reports corrupted blocks after HBase reinstall
Date Tue, 26 Apr 2011 23:56:52 GMT
Unless HBase was running when you wiped that out (and even then), I
don't see how this could happen. Could you match those blocks to the
files using fsck and figure when the files were created and if they
were part of the old install?

Thx,
