Limitations of Phoenix-Hive connector

Following are some of the limitations of Phoenix-Hive connector:

  • Only 4K character specification is allowed to specify a full table. If the volume of the data is huge, then there is a possibility to lose the metadata information.
  • There is a difference in the way timestamp is saved in Phoenix and Hive. Phoenix uses binary format, whereas Hive uses a text format to store data.

  • Hive LLAP is not supported in this integration.

  • As of HDP 3.0, the MapReduce engine for Hive is deprecated. Similarly, this tool is not guaranteed to work with the MapReduce engine.
