Re: dump HLog content!

Thanks for your reply. After nearly 60minutes, I can see the Hlog volume.

-rw-r--r--   3 yonghu supergroup       2125 2012-04-15 17:34
/hbase/.logs/yonghu-laptop,60020,1334504008467/yonghu-laptop%2C60020%2C1334504008467.1334504048854

I have no idea why it takes so long time.
