Problem Note 58847: Reading SAS® Scalable Performance Data (SPD) Engine data with the serializer/deserializer (serde) from Hadoop Hive using Map-Reduce generates errors
 |  |  |  |  |
The SAS Scalable Performance Data (SPD) Engine creates SAS® data sets on a Hadoop Distributed File System (HDFS). The serializer/deserializer (serde) provided by SAS enables read access to these tables directly from Hive.
SAS supplies an InputFormat with the serde. The InputFormat has custom methods to ensure that the data is split on even multiples of the SPD record length. This ensures that each split occurs on a record boundary and contains only complete records.
When the Hive query does not require a Map-Reduce job to process the query, it uses the SAS InputFormat.
However, when Hive starts a Map-Reduce job to process a query, Map-Reduce uses its own InputFormat rather than the InputFormat provided by SAS. This causes the splits that come into the Map-Reduce job to potentially not be on a record boundary, but instead might start and/or end in the middle of a record. Error messages like the following are generated when this occurs:
