Hi, I have a use case in HBase + Hive Integration where HBase primary key is a composite key and the keys is separated by us with a custom delimiter. So basically it is Key = A~B~C. Now, I wanted to run a query on this HBase table using Hive and group by "A" (and not the complete primary key). I went through the following presentation : https://docs.google.com/viewer?a=v&q=cache:GHg9GMFOZVwJ:assets.en.oreilly.com/1/event/61/HBase%2520and%2520Hive%2520at%2520StumbleUpon%2520Presentation.ppt+hbase+composite+key+hive&hl=en&gl=us&pid=bl&srcid=ADGEEShTyoUXyvXptTu4pMjje_FkaN_j1OK9wG0lclWWsKNjGreLTkk3IDqT16xO8ClqIfzhM69aeU7Gph4kZPxTS-PXvLiWPSRvgS2WEjnvViPJhpM0ItsLaTWq1DRuUgOzKhjSzIlx&sig=AHIEtbT4scO3IdtvLYG3RtLoKN5gG1udPg
It says that this was implemented at StumbleUpon, anybody having any idea if that can be used by others. Also, there is this issue in JIRA : https://issues.apache.org/jira/browse/HIVE-2599 which talks about similar feature. So it would be very helpful if anyone can give me some idea regarding this.
