[jira] [Commented] (HDFS-16870) Client ip should also be recorded when NameNode is processing reportBadBlocks
[ https://issues.apache.org/jira/browse/HDFS-16870?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17648885#comment-17648885 ]
ASF GitHub Bot commented on HDFS-16870:
---------------------------------------
Daniel-009497 opened a new pull request, #5237:
URL: https://github.com/apache/hadoop/pull/5237
There are two scenatio involded for reportBadBlocks
1-HDFS client will report bad block to NameNode once the block size or data is not consistent with meta;
2-DataNode will report bad block to NameNode via heartbeat if Replica stored on Datanode is corrupted or be modified.
As for now, when namenode process reportBadBlock rpc request, only DataNode address is logged.
Client Ip should also be logged to distinguish where the report comes from, which is very useful for trouble shooting.
