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: hadoop-telles-844fb3f0-dfd8-456d-89c3-1d7cfdbdcad2/10.3.2.99:49911. 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? Thanks
