Summary: Command line to force volume failures
Key: HDFS-14571
URL: https://issues.apache.org/jira/browse/HDFS-14571
Project: Hadoop HDFS
Issue Type: New Feature
Components: datanode, hdfs
Environment: Linux
Reporter: Scott A. Wehner
Datanodes that have failed hard drives reports to the namenode that it has a
failed volume in line with enabling slow datanode detection and we have a
failing drive that has not failed, or has uncorrectable sectors, I want to be
able to run a command to force fail a datanode volume based on storageID or
Target Storage location (a.k.a mount point).
