Lefty Leverenz commented on HIVE-9453:
--------------------------------------
Doc note: This adds three configuration properties to HiveConf.java in the
HBase-metastore branch, so they will need to be documented in the wiki when the
branch gets merged to trunk. Adding a TODOC-1.2 label because that's currently
shown as the fix version.
* hive.metastore.fastpath
* hive.metastore.hbase.cache.size
* hive.metastore.hbase.cache.ttl
(I have some quibbles with the parameter descriptions, which can be fixed in
the trunk merge.)
> Initial patch [hbase-metastore branch]
> --------------------------------------

> Key: HIVE-9453
> URL: https://issues.apache.org/jira/browse/HIVE-9453
> Project: Hive
> Issue Type: Sub-task

> Reporter: Alan Gates

> This initial patch has several important features:
> # HBaseStore, a new implementation of RawStore that stores the data in HBase.
> # Subclasses of the thrift metastore objects to remove the massive
> duplication of data where every partition contains a nearly identical storage
> descriptor.
> # Caches for catalog objects and statistics so that repeated metastore calls
> don't result in repeated calls against HBase.
> Currently this "works" to the point that "load table" and "select" work. I
> have not tested any other statements, and I suspect most fail. There is no
> security, no authorization, and a no a lot of other things.
