Description
A run of ap_pipe on ap_verify_hits2015, visit=411657, and no CCDs in the dataId failed on CCD 35 with a Butler error about no defects existing. This error did not occur when running CCD 35 by itself, or with ccdnum=33..38, suggesting it's associated with large parallel runs.
Given that defects are read-only from ap_pipe's point of view, this may be a bug in the Butler rather than ap_pipe.
My initial report was wrong; the failure happens with CCD 2, not CCD 35 (I got confused because it's HDU 35). It does occur if I just run CCD 2 by itself, including in single-threaded mode. The root cause is no defect file ingested for that CCD.
Since it's not a race condition, or even a bug in the defects code, I'm closing this issue as invalid.
