Titan 1.0.0

Hadoop versions and Titan 1.0.0

Titan 1.0.0 itself is compatible with both Hadoop 1 and 2, but TinkerPop’s hadoop-gremlin requires Hadoop 1. hadoop-gremlin contains graph computer implementations for running traversals on Spark and Giraph, among other bits.

This will change in later TinkerPop releases. Titan 1.0.0 depends on TinkerPop 3.0.1-incubating. However, support for Hadoop 2 has been announced for the TinkerPop 3.1.0 release: https://groups.google.com/d/msg/gremlin-users/VB5D61L-xm8/_0MKqcTdAQAJ

Once TinkerPop 3.1.0 is released, subsequent Titan can restore full Hadoop 2 support. Hadoop 1 support will be retained if doing so is painless; if it raises conflicts, then it may be dropped.

However, for Titan 1.0.0 with TinkerPop 3.0.1-incubating, the situation is reversed: only Hadoop 1 can be fully supported in the zipfile distribution on account of hadoop-gremlin, and Hadoop 2 support is offered only insofar as conflicts around hadoop-gremlin can be avoided. The Hadoop 1 zipfile offers all of the functionality of its Hadoop 2 counterpart, except that it lacks titan-solr and it can’t talk to Hadoop 2 clusters (generally including HBase clusters running on top of Hadoop 2). The Hadoop 2 zipfile is missing the following features compared with its Hadoop 1 counterpart:

  • The Hadoop 2 zipfile lacks titan-hadoop and hadoop-gremlin
  • The Hadoop 2 zipfile lacks MapReduceIndexJobs
  • The Hadoop 2 zipfile is not as well-tested as the Hadoop 1 zipfile; it’s possible that other bits are broken but yet undiscovered
