  • Migrating from 1.x.x to 1.10.0 
    • The "Auto-Create Partitions" property was removed from the PutHive3Streaming processor, causing existing instances of this processor to become invalid. The property would appear as a unsupported user-defined property and must be removed to return the processor to a valid state.
    • The Zookeeper dependency that NiFi uses for state management and cluster elections was upgraded to v3.5.5. From v3.5.x onwards, Zookeeper changed the zookeeper.properties file format and as a result NiFi users using an existing embedded zookeeper will need to adjust their existing zookeeper.properties file accordingly. More details here: https://zookeeper.apache.org/doc/r3.5.3-beta/zookeeperReconfig.html#sc_reconfig_clientport.
      For new deployments of the 1.10.0 release onwards, NiFi will be packaged with an updated template zookeeper.properties file.
      To update an existing zookeeper.properties file however, edit the conf/zookeeper.properties file:
      1. Remove the clientPort=2181 line (or whatever your port number may be)
      2. Add the client port to the end of the server string eg: server.1=localhost:2888:3888;2181
  • Migrating from 1.x.x to 1.9.0 
    • Schema validation changed for ConvertAvroSchema, ConvertCSVToAvro, ConvertJSONToAvro processors. If using an URI to locate the schema file, a scheme such as file://, hdfs://, etc, must be specified, otherwise the processor will be considered as invalid.
