Summary: Kylin MapR-DB Storage Connector
Key: KYLIN-2750
URL: https://issues.apache.org/jira/browse/KYLIN-2750
Project: Kylin
Issue Type: New Feature
Reporter: nirav patel
Assignee: nirav patel
Kylin currently only supports Hbase as a storage engine. MapR-DB is a
proprietary version of Hbase. Out of the box kylin cube engine is able to
create cubes (hfile, htable) on mapr and mapr can treat as either hbase or
maprdb table. However issue arise while trying to query these tables as MapR-DB
doesn't support coprocessor service offered by standard hbase. Kylin relies
heavily on coprocessor service for aggregation, projection and distributed
computation.
As a maprdb doesn't supports coprocessor kylin query engine throws following
error:
"coprocessorService is not supported for MapR"
Proposal to fully support MapR-DB on kylin
# Create maprdb-storage adapter to store cubes and metadata on maprdb instead
of hbase
# To improve performance of query, add support for Drill or Spark DataFrame to
query specific cube
