Summary: Increase of time between steps after Kylin 2.3.1 update
Key: KYLIN-3371
URL: https://issues.apache.org/jira/browse/KYLIN-3371
Project: Kylin
Issue Type: Bug

Environment: -EMR 5.7 (S3 storage for Hive and HBase)
-Kylin 2.3.1 (updated from 2.2). Deployed on separated EC2 instance.

Hi,
We have updated from Kylin 2.2 to Kylin 2.3.1. We performed the update process
with successful. However, we have experimented an increase of time wasted
between steps during building time. For example, the time between step 7 “Build
N-Dimension Cuboid:level 1” and “…level2” is now about 30 seconds, a lot of
time if we take into account that in these steps no processing is executed
since we use the "layer" algorithm (Screenshot 1). This time between steps is
much longer than when we used Kylin 2.2, were average time was about 5 seconds.
(Screenshot 2).
Could it be related to a change in the code? The configuration we use in Kylin
2.3.1 is the same as we used in Kylin 2.2. I have considered this JIRA as a
possible BUG.
Thanks in advance,
