[jira] [Created] (KYLIN-2334) Investigate using HDFS as Kylin metadata store

Shaofeng SHI created KYLIN-2334:
-----------------------------------

             Summary: Investigate using HDFS as Kylin metadata store
                 Key: KYLIN-2334
                 URL: https://issues.apache.org/jira/browse/KYLIN-2334
             Project: Kylin
          Issue Type: Task
          Components: Metadata
            Reporter: Shaofeng SHI
            Assignee: Shaofeng SHI


Today Kylin's metadata is stored in HBase, each time when submitting a job, need dump the files to local and then submit to hadoop for parallel computing (avoid massive access to HBase from mappers)

If HDFS can natively be used as the storage for Kylin metadata (with similar read/write performance), the process will be much simplified.
