Hi, I've read that on a modern hardware I should increase the value of io.file.buffer.size parameter of HDFS, up to 128kb or so. [1] Does this advice still hold true in the context of HBase? We've done a series of performance benchmarks with the different values of it, but couldn't observe a noticeable difference in performance. Is the default 4kb good enough? What is the recommended value, or maybe it doesn't matter?
Thanks in advance. [1]: Book: Hadoop - The Definitive Guide
