Constructor Detail

FillDiskCommandAction

public FillDiskCommandAction(long size,
                             long duration,
                             String path,
                             long timeout)

Fill the disk on a random regionserver. Please note that the file will be created regardless of the set duration or timeout. So please use timeout and duration big enough to avoid complication caused by retries.

Parameters:

size - size of the generated file in MB or fill the disk if set to 0

duration - the time this issue persists in milliseconds

path - the path to the generated file

timeout - the timeout for executing required commands on the region server in milliseconds
