  • Migrating from 1.x.x to 1.11.0
    • CompressContent has been updated to specify the compression level when using XZ-LZMA2 compression whereas before it was unspecified.  The default is level 1 now.  If you wish to see higher levels of compression (and CPU effort) you might wish to set this value higher. CompressContent had previously only used that property for GZIP compression.
  • Migrating from 1.x.x to 1.10.0 
    • The RPM creation mechanism appears broken for both Java 8 and Java 11 binaries if you wanted to build those yourself.  Should be resolved in a later release.
    • We've removed the following nars from the default convenience binary.  These include kite-nar, kafka-0-8-nar, flume-nar, media-nar, druid-controller-service-api-nar, druid-nar, other-graph-services-nar.  You can still get them from the various artifact repositories and use them in your flows but we cannot bundle them due to space limitations by default.
    • 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
