James Taylor commented on OMID-110:
-----------------------------------
[~yonigo] - any progress on this one? FWIW, the way Tephra does compat modules
works pretty well. They have the HBase dependencies specified in their shim
module. Other projects that want to use Tephra specify two dependencies: the
tephra core dependency and the tephra compat module (based on the version of
HBase they use).
> Support HBase 2.0

> Key: OMID-110
> URL: https://issues.apache.org/jira/browse/OMID-110
> Project: Apache Omid
> Issue Type: Improvement
> Reporter: James Taylor
> Assignee: Yonatan Gottesman
> Priority: Major
> Attachments: OMID-110_wip1.patch

>
> Once OMID-107 is committed (which replaced all deprecated methods), the only
> things I've identified that need to change are:
> * Instantiation of CellComparator should be done through HBaseShims since
> it's different between HBase 1.x and 2.x. In HBase 2.0, CellComparator was
> changed to an interface. Another alternative would be to write our own
> CellComparator.
> {code:java}
> public static SortedMap<Cell, Optional<Cell>>
> mapCellsToShadowCells(List<Cell> cells) {
> // Move CellComparator to HBaseSims for 2.0 support
> // Need to access through CellComparatorImpl.COMPARATOR
> SortedMap<Cell, Optional<Cell>> cellToShadowCellMap
> = new TreeMap<Cell, Optional<Cell>>(new CellComparator());{code}
> The HBase 2.0 version would use CellComparatorImpl.COMPARATOR instead of
> instantiating a CellComparator.
> * Add createTable method to HBaseShims. Instead of HTableDescriptor, HBase
> 2.0 uses TableDescriptor and TableDescriptorBuilder.
> [~chrajeshbab...@gmail.com] and [~an...@apache.org] - do you know why
> existing admin.createTable(HTableDescriptor) wouldn't work? HTableDescriptor
> implements TableDescriptor.
