Subject Max Connect retries
Date Sun, 08 Feb 2015 04:37:55 GMT
Hi, I changed my cluster config so a failed nodemanager can be detected in
about 30 seconds. When I'm running a wordcount the reduce gets stuck in 25%
for a quite while and logs show nodes trying to connect to the failed node:

org.apache.hadoop.ipc.Client: Retrying connect to server:
Already tried 28 time(s); maxRetries=45
2015-02-08 04:26:42,088 INFO [IPC Server handler 16 on 50037]
org.apache.hadoop.mapred.TaskAttemptListenerImpl: MapCompletionEvents
request from attempt_1423319128424_0025_r_000000_0. startIndex 24
maxEvents 10000

Is this the expected behaviour? should I change max retries to a lower
values? if so, which  config is that?
