BUG: HiveStreaming processor not picking the updated hive-meta store principal from hive-site. xml
1. Copy hive-site.xml, core-site.xml, hdfs-site.xml to the conf directory of NiFi
2. Clear the Hive Configuration Resources property
3. Create an ExecuteStream processor on the canvas scheduled to run as often as the ticket needs to be refreshed (every hour should do for most setups) with the following groovy script, replacing nifi@HDF.COM with your principal and /etc/nifi.headless.keytab with your keytab
Steps: Create /etc/hdp/tgt.groovy and copy the code below into the file on all nifi nodes.
Note: Change the kerberos principal and keytab location as necessary
