Thejas M Nair commented on HIVE-9578:
-------------------------------------
* The hbase doc doesn't clearly say what regex syntax is supposed by
RegexStringComparator, so I assume it is the java regex. The regex syntax
supported by 'show databases' is different. See [show database
doc|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Show]
. Looks like we need to translate the way ObjectStore.getDatbases does.
* What tests go into TestHBaseStoreIntegration vs TestHBaseStore. It seems
like the tests added to TestHBaseStoreIntegration could be added in
TestHBaseStore as well.
> Add support for getDatabases and alterDatabase calls [hbase-metastore branch]

> the databases, and getting database names by pattern.
