Arpit Agarwal commented on HDFS-11477:
--------------------------------------
Jenkins rightly flagged the v2 patch compile error but I looked at the wrong
Jenkins output I think.
Still doesn't explain why the v1 patch compilation succeeded.
> Simplify file IO profiling configuration

> For Profiling FileIO events, there are 2 keys:
> - DFS_DATANODE_ENABLE_FILEIO_PROFILING_KEY for enabling the hooks
> - DFS_DATANODE_FILEIO_PROFILING_SAMPLING_FRACTION_KEY for setting the
> sampling fraction
> We can instead have only the sampling fraction key and set it to 0 if we want
> to disable profiling.
