Alexey Serbin commented on KUDU-3317:
-------------------------------------
I don't think that's a bug in Kudu. Those messages most likely are there due
an HTTP client sending in requests and dropping connections prematurely.
Maybe, somebody tries to exploit some vulnerability in the mangoose/squeasel
server which Kudu uses as the embedded web server or that's an attempt of a DoS
attack?
I'd suggest to clarify what's the source IP of those requests: it seems
squeasel doesn't report that information, but it's possible to check for the
state of TCP connections using, say, the {{netstat}} tool and by other means.
