Teng Yutong updated HIVE-6584:
------------------------------
Attachment: HIVE-6584.5.patch
hi,
this patch is my current workaround when dealing with HBase snapshot.
but in order to make this patch work, still some changes is needed on the HBase
side (change the visible descriptor of
mapreduce.TableMapReduceUitls.convertStringToScan and
mapreduce.TableSnapshotInputFormat.TableSnapshotRegionSplit into public).
Since there is no issue related to this in HBase JIRA, so i haven't create a
patch for these changes.

> HBASE-8369 provided mapreduce support for reading from HBase table snapsopts.
> This allows a MR job to consume a stable, read-only view of an HBase table
> directly off of HDFS. Bypassing the online region server API provides a nice
> performance boost for the full scan. HBASE-10642 is backporting that feature
> to 0.94/0.96 and also adding a {{mapred}} implementation. Once that's
> available, we should add an input format. A follow-on patch could work out
> how to integrate this functionality into the StorageHandler, similar to how
> HIVE-6473 integrates the HFileOutputFormat into existing table definitions.
