I see Presto has plugin only to CDH4. Can I connect to other distributions such as HortonWorks from this and what does it take to do it. Without a specific plugin, I am running into "path host null" errors when executing queries from Presto. Appreciate your help.

The Presto Hive connector supports multiple versions of Hadoop:

  • hive-hadoop1: Apache Hadoop 1.x
  • hive-hadoop2: Apache Hadoop 2.x
  • hive-cdh4: Cloudera CDH 4
  • hive-cdh5: Cloudera CDH 5

See the Hive Connector documentation for more details.

  • The plugin's pom has a dependency on hive-cdh4: https://github.com/facebook/presto/blob/master/presto-hive-cdh4/pom.xml The source for the hive-cdh4 artifact is here: https://github.com/facebook/presto-hadoop-cdh4 The actual code for the Hive connector is here: https://github.com/facebook/presto/tree/master/presto-hive – David Phillips Nov 13 '13 at 19:21
