thanks a lot,i will check KYLIN-1936 and try v1.5.4 to find if it will solve
our problem by use "select * from table limit N"

"limit",how can we deal with this one?

some sub directory for example:

above was the hbase operation beginning;the reduce job was trying to

get hbase related configuration ,especiall the very "hbase.zookeeper.quorum"

within ldap non-admin user,HiveColumnCardinalityJob fail with
mapreduce.job.queue defined in file kylin_job.xml
and i notice same issue fixed by KYLIN-955 after kylin 1.3,but why it still
not work on my kylin 1.5.1(hadoop 2.4.1)?
i review the related patch,and suspect for the following code

the above kylin.metadata.url with namespace works fine with hbase

the error happens in
./job/src/main/java/org/apache/kylin/job/JoinedFlatTable.java with function
generateCreateTableStatement,where the second parameter
14 matches
