Karthik Palanisamy commented on HDFS-14164: ------------------------------------------- [~bharatviswa] Backup Namenode keeps unreachable safemode threshold. Would not be able to fix some of these test cases. [~szetszwo] any plan on this [HDFS-4114|https://issues.apache.org/jira/browse/HDFS-4114]. I will do change accordingly. > Namenode should not be started if safemode threshold is out of boundary > ----------------------------------------------------------------------- > > Key: HDFS-14164 > URL: https://issues.apache.org/jira/browse/HDFS-14164 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 2.7.3, 3.1.1 > Environment: #apache hadoop-3.1.1 > Reporter: Karthik Palanisamy > Assignee: Karthik Palanisamy > Priority: Minor > Labels: patch > Attachments: HDFS-14164-001.patch, HDFS-14164-002.patch, > HDFS-14164-003.patch > > > Mistakenly, User has configured safemode > threshold(dfs.namenode.safemode.threshold-pct) to 090 instead of 0.90. Due to > this change, UI has the incorrect summary and it never turns to be out of > safemode until manual intervention. Because total block count will never > match with an additional block count, which is to be reported. > I.e > {code:java} > Wrong setting: dfs.namenode.safemode.threshold-pct=090 > Summary: > Safe mode is ON. The reported blocks 0 needs additional 360 blocks to reach > the threshold 90.0000 of total blocks 4. The number of live datanodes 3 has > reached the minimum number 0. Safe mode will be turned off automatically once > the thresholds have been reached. > 10 files and directories, 4 blocks (4 replicated blocks, 0 erasure coded > block groups) = 14 total filesystem object(s). > {code} > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
