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.
