    Description

       Apache Hive is currently on 1.5.X version and in order to take advantage of the latest ORC improvements such as column encryption we have to bump to 1.6.X.

      https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12343288&styleName=&projectId=12318320&Create=Create&atl_token=A5KQ-2QAV-T4JA-FDED_4ae78f19321c7fb1e7f337fba1dd90af751d8810_lin

      Even though ORC reader could work out of the box, HIVE LLAP is heavily depending on internal ORC APIs e.g., to retrieve and store File Footers, Tails, streams – un/compress RG data etc. As there ware many internal changes from 1.5 to 1.6 (Input stream offsets, relative BufferChunks etc.) the upgrade is not straightforward.

      This Umbrella Jira tracks this upgrade effort.
