[jira] [Created] (NIFI-5065) HTTP Site-to-Site fails sending data
more than 2GB at once
Koji Kawamura created NIFI-5065:
-----------------------------------
Summary: HTTP Site-to-Site fails sending data more than 2GB at once
Key: NIFI-5065
URL: https://issues.apache.org/jira/browse/NIFI-5065
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.0.0
Reporter: Koji Kawamura
Assignee: Koji Kawamura
NiFi Site-to-Site (S2S) is designed to support sending large files. While RAW transport protocol works fine with large files (I tested up to 8GB, but it can be more), HTTP transport protocol starts failing if more than 2GB data is sent at a time, meaning by sending a 2GB FlowFile, or batching multiple FlowFiles to make more than 2GB into one transaction.
When it fails, following log messages are written:

The cause of this issue is that SiteToSiteRestApiClient.openConnectionForSend method uses int variables to track bytes it sends. When the total size exceeds Integer.MAX_VALUE, the int variables get overflown. Then the check condition goes wrong.
