DFSOutputStream.writeChunk() enqueues packets into data queue and after that it returns. So write is asynchronous.
I want to know the total actual time of HDFS executing the write operation (start from writeChunk() to the time that each replication is written on disk). How can get that time? Thanks. -- View this message in context: http://www.nabble.com/How-can-I-get-the-actual-time-for-one-write-operation-in-HDFS--tp23516363p23516363.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
