Key: HDFS-9087
URL: https://issues.apache.org/jira/browse/HDFS-9087
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Affects Versions: 2.6.0
Reporter: Elliott Clark
Assignee: Elliott Clark
If all datanodes are started across a cluster at the same time (or errors in
the network cause ioexceptions) there can be storms where lots of datanodes
check their disks at the exact same time.
