at org.apache.kylin.job.hadoop.hbase.BulkLoadJob.run(BulkLoadJob.java:75) Here Kylin is setting the permission of generated HFile so HBase can take over. My feeling is something wrong with the HFile. Click the key icon under the GUI step, you shall see a popup like
"-input /apps/hdmi-prod/b_kylin/qa/kylin-938b48a3-a9e8-472e-b9e2-f50bc2a16778/xxxx/hfile/ -htablename KYLIN_LLCVWUB5Y4 -cubename xxxx" The input is the HFile directory the permission error is about. Check it on HDFS. Cheers Yang On Tue, Jun 2, 2015 at 10:23 AM, Diego Pinheiro <[email protected]> wrote: > Hi there, > > I started playing around with Kylin by making an simple example.
