------------------------------------
Summary: Azure Blob access no longer works on 2.7.2
Key: NIFI-15500
URL: https://issues.apache.org/jira/browse/NIFI-15500
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 2.7.2
Environment: All
Reporter: Craig Patrick
Since upgrading to 2.7.2 from 2.0.0, all of our Azure Blob processors have
failed to work which is causing a major issue for us - the error we are seeing
is this:
{code:java}
PutAzureBlobStorage_v12[id=ea118bcc-019b-1000-c292-55693713826e] Processing
halted: yielding [1 sec]: java.lang.NoClassDefFoundError: Could not initialize
class reactor.netty.http.client.HttpClientSecure - Caused by:
java.lang.ExceptionInInitializerError: Exception
java.lang.NoClassDefFoundError: io/netty/handler/codec/quic/Quic [in thread
"Timer-Driven Process Thread-6"]{code}
in the logs on startup, I'm seeing this:
{code:java}

Is this a known issue, is there a workaround or is this fixed in a patch?
