Subject HDFS append overhead
Date Tue, 21 May 2013 18:52:47 GMT
I am trying to determine if it is feasible for multiple nodes to alternate appends to a shared
file in HDFS.
Can someone tell me, what is the overhead of an open/append/close cycle?
If multiple nodes attempt open-for-append at once, the losers queue nicely waiting for the
winner to close?
