Subject Encountered problems when prefetch META table
Date Fri, 19 Jul 2013 21:29:06 GMT
Hello, I'm a newbie to Hadoop HBase.
I downloaded and installed Hadoop Traning Ubundu Image (Cloudera
Distribution for Hadoop).
When I tried to create a table and create put instances using java API. I
got the following error. Could anybody help me out? Thanks!
