When using oozie, we encountered the following exception

Serverredirectedtoomanytimes(20)
java.net.ProtocolE xception:Serverredirectedtoomanytimes (20)
atsun.net. www.protocol.http.HttpURLConnection.getInputStream (HttpURLConnection. java:1141 )
atjava.net.URL.openStream(URL. java:1007 )

What’s the matter with this

Later, it was found in the forum that someone mentioned:

“Most of the redirection is back to the original page.”

That is to say, after jumping to one address, because it fails to pass the verification, it does not jump to the next address

Or return to the current address

As a result, the same address constantly jumps back to itself, becoming a dead loop

After 20 times, it was reported as abnormal
