Subject [jira] Commented: (HADOOP-3193) Discovery of corrupt block reported in name node log
Date Wed, 14 May 2008 21:33:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596947#action_12596947

lohit vijayarenu commented on HADOOP-3193:
------------------------------------------

+1 patch looks good. One small thing, the metric seem to report number of corrupt blocks reported
over time. Should it be changed to number of corrupt blocks in the system at any point of
time, possibly using MetricsIntValue. And also, namesystem.markBlockAsCorrupt  logs a message
about  this inside corruptReplicas.addToCorruptReplicasMap function.
