issure about output of "hdfs dfsadmin -metasave"
hi,all:
i dump the info to a file use
# hdfs dfsadmin -metasave mysave
Created metasave file mysave in the log directory of namenode
hdfs://CH22:9000
# find /var -name 'mysave'
/var/log/hadoop-hdfs/mysave
when i read the mysave file ,some fields in record confuse me
/tmp/hadoop-mapred/mapred/staging/root/.staging/job_201307081702_0002/libjars/zookeeper-3.3.5-cdh3u4.jar:
blk_-13468897528190974_20279 (replicas: l: 3 d: 0 c: 0 e: 0)
192.168.10.35:50011 : 192.168.10.36:50011 : 192.168.10.34:50011 :
for example,from the content "replicas: l: 3 d: 0 c: 0 e: 0",it seems some
kind of replicas status,but
i do not know exact means of "l d c e",anyone can help?

You can find the codes in "BlockManager.java" :)
