Re: could only be replicated to 0: TL;DR
If the datanode is definitely not running out of space, and the overall system has basically been working leading up to the "replicated to 0 nodes" error (which proves the configuration and permissions are all basically correct), then what other explanations are there for why hdfs would suddenly start exhibiting this error out of the blue?
Thanks.
