Hello, I'm a student from SCUT.I'm interested in big data.Recently I want to
test the big data query ability of kylin,and met some problem that bother me
for a month.I'm new here and eager to get your help, thank you!
1.I load tables to hive by ETLtool kettle sucessfully,but when I try to load
them to kylin ,it told me success but the table size is null.So I try to add my
my table sql to kylin's create_sample_tables.sql, It create sucessfully this
time but it obviously not a good way to create tables . what's the difference
between these two method. And how can I load tables to kylin from hive in
normal way.
2. When I build the sample cube ,It met error on the penultimate step ,the
error information is: org.apache.hadoop.security.AccessControlException:
Permission denied. user=root is not the owner of inode=null. It seem like a
permission problem, and I can't find the way out.
3.I want to test the big data query ability,about 1 billion,but kylin set its
threshold value as 2 million. I found the threshold setting in source code
DictionaryGenerator.java . Are there any other threshold setting? And what's
next after I change the threshold value.
yours, sincerely.
