The run-time of Hive unit tests are high as need to operate on the disk > quite often. > 2. It can cause conflict if multiple test cases operates on the same table > name (such as table being created already exist). > To solve these problems, we shall use an in-memory storage option of Derby DB > which can be even persisted if the test case demands that. > https://db.apache.org/derby/docs/10.8/devguide/cdevdvlpinmemdb.html -- This message was sent by Atlassian JIRA (v6.3.15#6346)
