-----------------------------------
Summary: Streaming cubing doesn't generate cuboids files on HDFS,
cause cube merge failure
Key: KYLIN-1387
URL: https://issues.apache.org/jira/browse/KYLIN-1387
Project: Kylin
Issue Type: Bug
Components: streaming
Affects Versions: v2.0
Reporter: Shaofeng SHI
Assignee: Shaofeng SHI
Fix For: v2.1
In an early version of Kylin streaming, the HBaseMROutput2.java will use HBase
Scan API to do the merge. Later Yang refactored that into
HBaseMROutput2Transition.java, while keep using the cuboids files on HDFS to do
the merge. But the StreamingBatchBuilder didn't generate the cuboids, which
causes the merge failed to run.
Solution: as a workaround, the StreamingBatchBuilder should leave cuboids files
when building micro segments.
