Sailesh Mukil commented on HDFS-11531:
--------------------------------------
Thanks for the comments [~cmccabe], I will address them after clarifying the
below.
> Why not just return the hdfsHedgedReadMetrics pointer? The error is in errno
> anyway on a failure.
I agree. However, I was following the same API style exposed by
hdfsFileGetReadStatistics() and hdfsFileFreeReadStatistics():
https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs/hdfs.c#L96
If you still think I should change it to return the struct, I can go ahead and
do so.
