Greetings, I've been tinkering with HDFS, and I'm a bit confused about its alleged immutability. Basically, according to the interwebz (and my interpretation of the documentation), data in HDFS is immutable.
However, when I tell the HDFS Java client to overwrite an existing file with garbage, it happily does so without complaining. That doesn't really match my definition of immutability. What I'm looking for is a way to allow users to create (and maybe append to) files, but *prevent* them from updating/deleting/overwriting data. One which isn't a client configuration option. Am I missing some kind of configuration option which enables this sort of behaviour? Or am I chasing a pipe dream? Thanks, - Bram --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
