Mingliang Liu commented on HDFS-11088: -------------------------------------- I think the proposal and the solution make sense. Thanks for pinging me [~andrew.wang]. {quote} I think we can file another JIRA to make a change if we think it's necessary to do here. This JIRA will be better to focus on the change as the this JIRA's title mentioned. {quote} I think we should add the check in this patch as it is needed largely because we're changing the "force" parameter in {{activate()}}. If "force" is true as it was, we can ignore the return value blindly in that it is supposed to return true after leaving safe mode ignoring the orphan blocks (if any); here it becomes false, we'd better add Precondition check on the return value for safety. > Quash unnecessary safemode WARN message during NameNode startup > --------------------------------------------------------------- > > Key: HDFS-11088 > URL: https://issues.apache.org/jira/browse/HDFS-11088 > Project: Hadoop HDFS > Issue Type: Improvement > Affects Versions: 3.0.0-alpha1 > Reporter: Andrew Wang > Assignee: Yiqun Lin > Priority: Trivial > Labels: newbie > Attachments: HDFS-11088.001.patch, HDFS-11088.002.patch > > > I tried starting a NameNode on a freshly formatted cluster, and it produced > this WARN log: > {noformat} > 16/11/01 16:42:44 WARN blockmanagement.BlockManagerSafeMode: forceExit used > when normal exist would suffice.
