There isn't a concept of 'blacklist' in HDFS, it exists only in
MapReduce (MR1) and YARN.
Dead Nodes (and those that have been excluded) are reported via hdfs
dfsadmin -report as indicated earlier.

Hi,
Part answer: you can get the blacklisted tasktrackers using the command
line:
mapred job -list-blacklisted-trackers.
Also, I think that a blacklisted tasktracker becomes 'unblacklisted' if it
works fine after some time. Though I am not very sure about this.
Thanks
