Hi, I understand the way file upload happens on HDFS, where the data node asks the namenode for a pipe (64 MB) for writing chunks of the file to hdfs.
I want to change the source code of HDFS such that the datanode can have multiple pipes opens in parallel, where i push the data to the pipe based on it content. so my question is: 1- Is it possible? if yes, which classes might be responsible for that? 2- how can i track which classes/functions execute a command (for example when executing a hdfs put command.. how to trace the function calls between the namnode and datanode?). Thanks. -- Best Regards, Karim Ahmed Awara -- ------------------------------ This message and its contents, including attachments are intended solely for the original recipient.
