Hey All, For a while we've published binary packages with different Hadoop client's pre-bundled. We currently have three interfaces to a Hadoop cluster (a) the HDFS client (b) the YARN client (c) the Hive client.
Because (a) and (b) are supposed to be backwards compatible interfaces. My working assumption was that for the most part (modulo Hive) our packages work with *newer* Hadoop versions. For instance, our Hadoop 2.4 package should work with HDFS 2.6 and YARN 2.6. However, I have heard murmurings that these are not compatible in practice. So I have three questions I'd like to put out to the community: 1. Have people had difficulty using 2.4 packages with newer Hadoop versions? If so, what specific incompatibilities have you hit? 2. Have people had issues using our binary Hadoop packages in general with commercial or Apache Hadoop distro's, such that you have to build from source? 3. How would people feel about publishing a "bring your own Hadoop" binary, where you are required to point us to a local Hadoop distribution by setting HADOOP_HOME? This might be better for ensuring full compatibility: https://issues.apache.org/jira/browse/SPARK-6511 - Patrick --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@spark.apache.org For additional commands, e-mail: dev-h...@spark.apache.org
