Hi,
Is staging still used in hdfs when writing the data? This doubt
arose when I was going through the hdfs documents.
ref :
http://hadoop.apache.org/hdfs/docs/current/hdfs_design.html#Staging
I believe dfsclient does not cache the datablock
DFS client does not write the data to local disk first. Instead, it streams
data directly to the datanodes in the write pipeline. I will update the
document.
