>  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.
