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.

Was it helpful?

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.
