Hi, AFAIK, HIVE will use the derby for storing the metadata. I am not expert in HIVE, but i can give the some info. HIVE will store the table and hdfs path mappings ralated information in Derby. I think you can configure other DBs as well but by default Hive supports derby Regards, Uma - Or

[VOTE] Should we release 0.20.204.0rc2?

All, Matt rolled a 0.20.204.0rc1, but I think it got lost in the previous vote thread. Unfortunately, it had the version as 0.20.204 and didn't update the release notes. I've updated it, run the regression tests and I think we should release it. I've put the tarball up at: http://people.apach

Hadoop doesn't use derby. It does, however, use HSQLDB for its external DB I/O and example components. On Tue, Aug 9, 2011 at 3:43 PM, JSaravanaKumar wrote: > > can you please help me in understanding Why Derby is used along with Hadoop ? > -- > View this message in context: > http://old.nabble.

Uhm... Ok... I just did a quick Google search on Hadoop and Derby... https://issues.apache.org/jira/browse/HADOOP-4133 Then there's this subproject called Hive... :-) Oh and then there's this other subproject called Oozie... :-) Now Cloudera and other support MySQL in the role of Derby aka Clouds

Mike, Hive and Oozie are projects that build on top of Hadoop. Hadoop proper does not use Derby. Hope this clarifies. Thxs. Alejandro On Tue, Aug 9, 2011 at 1:38 PM, Segel, Mike wrote: > Uhm... > Ok... I just did a quick Google search on Hadoop and Derby... > https://issues.apache.org/jira/b

Right. The problem is how do you distinguish when someone is asking about the Hadoop (HDFS, MapReduce) And the Hadoop ecosystem. (HDFS, MapReduce, HBase, Hive, Pig, Oozie, Flume, etc ...) I interpreted the question to mean why are you using Derby in Oozie and Hive... :-) -Original Me

Oozie uses a SQL DB (it can be HSQLDB, DERBY, MYSQL, ORACLE) to persist the state of Oozie jobs. Thanks. Alejandro On Tue, Aug 9, 2011 at 1:48 PM, Segel, Mike wrote: > Right. > The problem is how do you distinguish when someone is asking about the > Hadoop (HDFS, MapReduce) > And the Hadoop ec
