[jira] [Work logged] (HDFS-16626) Under replicated blocks in dfsadmin report should contain pendingReconstruction‘s blocks
[ https://issues.apache.org/jira/browse/HDFS-16626?focusedWorklogId=779389&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-779389 ]

Work Description: lfxy opened a new pull request, #4416:
URL: https://github.com/apache/hadoop/pull/4416
[HDFS-16626](https://issues.apache.org/jira/browse/HDFS-16626)
In the output of command 'hdfs dfsadmin -report', the value of Under replicated blocks and ec Low redundancy block groups only contains the block number in BlockManager::neededReconstruction. It should also contain the block number in BlockManager::pendingReconstruction, include the timeout items. Specially, in some scenario, for example, decommission a dn with a lot of ec blocks, there would be a lot blocks in pendingReconstruction at a long time but neededReconstruction's size may be 0. That will confuse user and they can't access the real decommissioning progress.
