Hello,
I have installed HBase-0.90.4 on my local machine and as shown in "quick
start " i installed/configured in standalone mode using my local file
system of fedora-15. I have not started hadoop daemon assuming that its not
needed as its completely standalone config. All the required libs that
comes with the package are there. I faced lot of difficulty in compiling
the simple code itself.I set CLASSPATH, in hbase-env.sh set HBASE_CLASSPATH
but now it doen'n run. I took a code from the net and has created the
required table in the hbase.
When I am trying to execute a very basic java code using Hbase-0.90.4
API. some how it compiled but on execution it throws exception:
java MyLittleHBaseClient
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/commons/logging/LogFactory

Kindly see if any one has experienced the same issue at any point of time.
As for me its a long way ahead, hbase over HDFS and then hadoop
cluster.......
Thanks & Regards
