> Key: HDFS-3683
> URL: https://issues.apache.org/jira/browse/HDFS-3683
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 2.0.0-alpha
> Reporter: Todd Lipcon
> Assignee: Plamen Jeliazkov
> Priority: Minor
> Fix For: 2.0.2-alpha
>
> Attachments: HDFS_3683.patch, HDFS_3683.patch, HDFS_3683.patch

> When loading a large edit log, the NameNode prints a percentage-complete
> progress indicator:
> {code}
> int percent = Math.round((float)lastAppliedTxId / numTxns *
> 100);
> LOG.info("replaying edit log: " + lastAppliedTxId + "/" +
> numTxns
> + " transactions completed. (" + percent + "%)");
> {code}
> But the percentage is calculated incorrectly, since it divides the
> transaction ID by the number of expected transactions. This only works when
> starting at txid 1. (eg if we are loading 1000 transaction starting at txid
> 1000, the indicator will start at 100% and go to 200%)
