Question

Does Cloudera Impala capable of reading any Hive table (i.e. Customer SerDer) ? I couldn't find any such statement in their official documentation.

Était-ce utile?

La solution

Impala does not support custom Hive SerDes. From What features from relational databases or Hive are not available in Impala? in the Impala documentation available from Cloudera:

Custom Hive Serializer/Deserializer classes (SerDes). Impala supports a set of common native file formats that have built-in SerDes in CDH. See How Impala Works with Hadoop File Formats for details.
