Hellow,
The version of Hadoop used by me is hadoop-0.19.1 and the version of
hbase
used by me is hbase-0.19.3. I have put the files hadoop-0.19.1-core.jar and
hbase-0.19.3.jar in the lib
folder in hama.
I am getting the following exception when I try to create a random matrix. The
exception is first caught in
HColumnDescriptor.java. I am attaching that file for your convenience. As you
can
see on line 197 the HColumnDescriptor constructor is called. On line 201 this
constructor call a method isLegalFamilyName(familyName). If name does not end
with : an exception is being thrown
Also where are the log files stored ?
