							         Hello,  I would like to use PutDatabaseRecord, to insert to oracle tables milions of rows from JSON file. So i start with two records from json, but I came across a problem,  PutDatabaseRecord[id=70264994-b0a7-1501-0000-00003bbb7199] Failed to process StandardFlowFileRecord[uuid=afa320f6-9d5f-4e91-a7fc-abb3136464d0,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1533633308238-185, container=default, section=185], offset=567109, length=32],offset=0,name=1138608139480143,size=32] due to None of the fields in the record map to the columns defined by the ... table: 
  My flow for test:  Generateflowfile (JSON) --> PutDatabaseRecord (with JSONTreeReader)  I used different properties for processor PutDatabaseRecord for (Translate Field Names/Unmatched Field Behavior/Unmatched Column Behavior/Quote Column Identifiers/Quote Table Identifiers) base on this thread: none of the fields in the records map to the columns CSV to putDatabaseRecord  I also created flow with CSV flowfile, but nothing change, the same error occured  Table in database:  COLUMN NAME DATA TYPE  TEST_ID NUMBER  STRING VARCHAR2 (3000 CHAR)

							 ok you are right, for this kind of flow  but when I have for example:  - one flow for data acquisition from source to Cassandra in one process group  - second flow for data ingestion from Cassandra in another process group  How to set properties in Wait/Notify in this kind of flow ?   Unless there is also possible another solution ..

							     HI,  I would like to create data flow,which put file to one directory, and the if it has succeded, put the same file to another directory  I use for that Notify/Wait, but I wonder if uuid is a good solution for the signal,   Are Wait/Notify properties adequate ?   or if there is another way ?

							 If I understood you correctly, I download Drill 1.13.0  (https://drill.apache.org/download/) and I copied the driver from apache-drill-1.13.0/jars/jdbc-driver/drill-jdbc-all-1.13.0.jar to /var/lib/dlfs/lib/drill-jdbc-all-1.13.0.jar, where access has all nodes with NiFi,  but when I started processor , I got the following error      nifi-logs.txt
