Hi, I noticed that the mapper progress indication in the hadoop cdh3 distribution jumps from 0% to 100% for each gzipped input file. So when running with big gzipped input files the job appears to be stuck.
I was unable to find a jira issue that describes this effect. Before I dive into this I have a few questions to you guys: 1) is this a known effect for the 0.20 version? If so what is the jira issue? 2) is this specific to gzip? 3) is this effect still present in the MRv2/yarn version of Hadoop? Thanks. -- Met vriendelijke groet, Niels Basjes (Verstuurd vanaf mobiel )
