> Key: HDFS-9720
> URL: https://issues.apache.org/jira/browse/HDFS-9720
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: balancer & mover
> Affects Versions: HDFS-1312
> Reporter: Anu Engineer
> Assignee: Anu Engineer
> Fix For: HDFS-1312
>
> Attachments: HDFS-9720-HDFS-1312.001.patch,

>
>
> Add the following config params:
> # Max Disk Throughput - This allows users to control how much disk I/O is
> generated while disk balancer is running
> # Max Disk Errors - For each move operation, this allows user to specify how
> many I/O failures are tolerated before we declare the operation as failed.
> #Block Tolerance - Specifies how much movement of data is good enough. since
> the datanodes are active while the copy is going on, tolerance lets the user
> specify that if we reached something like 5% of projected Ideal storage on
> the destination disk, we can consider that move to be successful.
> Each of these parameter can be specified for each MoveStep. if not specified
> then the config parameters are used.
