I run a I/O test with M/R framework. Each mapper writes a 200M file to HDFs. I print the bytesRead and bytesWrite of FileSystem.Statistics every 1000ms. But I see these two values do not update immediately as the M/R progress forward. Anybody know the reason? Thanks. -- View this message in context: http://www.nabble.com/FileSystem.Statistics-does-not-update-at-once--tp23401667p23401667.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
