Lars Hofhansl resolved HBASE-11482. ----------------------------------- Resolution: Duplicate Fix Version/s: (was: 2.0.0) Closing as dupe of HBASE-13992. > Optimize HBase TableInput/OutputFormats for exposing tables and snapshots as > Spark RDDs > --------------------------------------------------------------------------------------- > > Key: HBASE-11482 > URL: https://issues.apache.org/jira/browse/HBASE-11482 > Project: HBase > Issue Type: New Feature > Components: mapreduce, spark > Reporter: Andrew Purtell > Assignee: Ted Malaska > > A core concept of Apache Spark is the resilient distributed dataset (RDD), a > "fault-tolerant collection of elements that can be operated on in parallel". > One can create a RDDs referencing a dataset in any external storage system > offering a Hadoop InputFormat, like HBase's TableInputFormat and > TableSnapshotInputFormat. > Insure the integration is reasonable and provides good performance. > Add the ability to save RDDs back to HBase with a {{saveAsHBaseTable}} > action, implicitly creating necessary schema on demand. > Add support for {{filter}} transformations that push predicates down to the > server as HBase filters. > Consider supporting conversions between Scala and Java types and HBase data > using the HBase types library. > Consider an option to lazily and automatically produce a snapshot only when > needed, in a coordinated way. (Concurrently executing workers may want to > materialize a table snapshot RDD at the same time.) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
