Akira AJISAKA commented on HDFS-8812:
-------------------------------------
I reproduced the error with AWS m3.xlarge instance but I couldn't with my
MacBook Air.
{code}
try {
byte[] buf = new byte[1024 * 1024];
peer.getOutputStream().write(buf);
Assert.fail("write should timeout");
} catch (SocketTimeoutException ste) {
{code}
It seems to me that {{peer.getOutputStream().write(buf)}} completed before
reaching the configured timeout (1 sec). I'm thinking smaller timeout and/or
bigger byte buffer will fix the problem.
