Yongjun Zhang commented on HDFS-11306: -------------------------------------- I saw [~jojochuang] has committed to trunk and branch-2 on 1/13/2017. Thanks Wei-Chiu! > Print remaining edit logs from buffer if edit log can't be rolled. > ------------------------------------------------------------------ > > Key: HDFS-11306 > URL: https://issues.apache.org/jira/browse/HDFS-11306 > Project: Hadoop HDFS > Issue Type: Improvement > Components: ha, namenode > Reporter: Wei-Chiu Chuang > Assignee: Wei-Chiu Chuang > Fix For: 2.9.0, 3.0.0-alpha2 > > Attachments: HDFS-11306.001.patch, HDFS-11306.002.patch, > HDFS-11306.003.patch > > > In HDFS-10943 [~yzhangal] reported that edit log can not be rolled due to > unexpected edit logs lingering in the buffer. > Unable to root cause the bug, I propose that we dump the remaining edit logs > in the buffer into namenode log, before crashing namenode. Use this new > capability to find the ops that sneaks into the buffer unexpectedly, and > hopefully catch the bug. > This effort is orthogonal, but related to HDFS-11292, which adds additional > informational logs to help debug this issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
