More Info from poster:
1. There are no failures, only warnings.
2. My config file has 2 nodes.
3. Only one of the warnings is still appearing. Please ignore the first one I reported.
4. Additionally, there is one information message after the warnings with the following report:
DateControl,0: Orchestrate Teradata Read Operator Summary
==========================================
Step Configuration:
-------------------
Total slave sessions: 100
Slave processes: 50
Nodes used: 2
Elapsed Times (in seconds):
---------------------------
Setup: 13
Reading from Teradata; 5
Disconnection: 4
Total: 22
Data Volume:
------------
Rows read: 3
Bytes read: 42
Rows rejected: 0
DateControl is the Teradata Enterprise stage.
I receive 47 warnings of the form:
DateControl,<n>: Insufficient blocks for partition <n>. Reading suppressed.
Where <n> ranges between 3-49.
My guess is that the query runs against each of the slave processes. Then some collection of the results occurs and a warning is generated for each slave that did not return a result.
