----------------------------------
Summary: SQL-to-Avro processors do not convert BIGINT correctly
Key: NIFI-2531
URL: https://issues.apache.org/jira/browse/NIFI-2531
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 0.7.0, 1.0.0
Reporter: Matt Burgess
Fix For: 1.0.0
For the SQL to Avro processors that use JdbcCommon (such as ExecuteSQL), if a
BigInteger object is being put into an Avro record, it is being put in as a
String. However when the Avro schema is created and the SQL type of the column
is BIGINT, the schema contains the expected type "long" (actually a union
between null and long to allow for null values). This causes errors such as:
UnresolvedUnionException: not in union: ["null", "long"]
If a BigInteger is retrieved from the result set and the SQL type is BIGINT,
then its value is expected to fit into 8 bytes and should thus be converted to
a long before storing in the Avro record.
