Subject [jira] [Commented] (CRUNCH-340) HCatSource
Date Sat, 22 Feb 2014 16:39:20 GMT


Chao Shi commented on CRUNCH-340:

[~jwills], I tested against hive 0.13 (not released). It should work on hadoop2 too.

According to [1], hive 0.13 will be released pretty soon. So I think this should be ready
for commit after several minor issues addressed (listed below):

1) pick one name: crunch-{hcat, hcatalog, hive}, {HCat, HCatalog, Hive}Source, From{HCat,
HCatalog, Hive}
2) add partition support

Please note that that there is a API change in hive 0.13 [2], so there needs a minor change
to get patch this compiled.

[2] HIVE-6185

I guess maybe we should create a new subproject (e.g. crunch-hcatalog) rather than add it
into crunch-core.
