[jira] [Created] (NIFI-5275) PostHTTP - Hung connections and zero reuse of existing connections

Steven Youtsey created NIFI-5275:
------------------------------------

             Summary: PostHTTP - Hung connections and zero reuse of existing connections
                 Key: NIFI-5275
                 URL: https://issues.apache.org/jira/browse/NIFI-5275
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.6.0
            Reporter: Steven Youtsey


Connection setups, the HEAD request, and the DELETE request do not have any timeout associated with them. When the remote server goes sideways, these actions will wait indefinitely and appear as being hung. See https://issues.apache.org/jira/browse/HTTPCLIENT-1892 for an explanation as to why the initial connection setups are not timing out.

Connections, though pooled, are not being re-used. A new connection is established for every POST. This creates a burden on highly loaded remote listener servers. Verified by both netstat and turning on Debug for org.apache.http.impl.conn.
