---------------------------------------
Summary: DataNodes with zero capacity and zero blocks should be
decommissioned immediately
Key: HDFS-15945
URL: https://issues.apache.org/jira/browse/HDFS-15945
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Takanobu Asanuma
Assignee: Takanobu Asanuma
Such as when there is a storage problem, DataNode capacity and block count
becomes zero.
When I tried to decommission those DataNodes, I ran into an issue that the
decommission did not complete because the NameNode had not received their first
block report.
I think those DataNodes should be decommissioned immediately even if they
haven't reported the first block report.
