[jira] Created: (HADOOP-7123) Hadoop Disk Fail Inplace
Hadoop Disk Fail Inplace
------------------------
Key: HADOOP-7123
URL: https://issues.apache.org/jira/browse/HADOOP-7123
Project: Hadoop Common
Issue Type: Improvement
Reporter: Bharath Mundlapudi
This is an umbrella Jira for tracking all the issues and work related for handling disk failures across the Hadoop stack. Today, Hadoop handles disk failures to some extent but not
all the issues. This involves understanding both startup and runtime issues related to disk failures in the Hadoop components.
Scope: The initial scope of work will only be for DataNode and TaskTracker related disk failure issues.
Methodology: Injecting disk failures in SCSI layer at various runtime points of Hadoop and observing Hadoop's behavior for improvement.

[jira] Commented: (HADOOP-7123) Hadoop Disk Fail Inplace

---------------------------------
Hi folks,
Could HDFS-1362 be treated as a solution on DataNode? Or any other features are required?
For now, HDFS-457 could stop service of failed disks and HDFS-1362 could add disks or re-enable disks after repaired them by means of reconfigure DataNode based on HADOOP-7001.
