Hi all ! I think I suceed using cephFS with hadoop, but I still face lost question for that I am a newer in hadoop and ceph! first, my ceph version is 0.62. java is 1.6.0_45 .hadoop is 1.1.2 I think suceed because: # hadoop fs -ls / drwxrwxrwx - root 0 2013-10-16 10:57 /libcephfs_junit but, when I use the commond hadoop dfsadmin -report, nothing printed on the terminal。 [] #hadoop dfsadmin -report [] # and then , I try some mapreduce's work! #hadoop jar hadoop-examples-1.1.2.jar wordcount /tmp/wordcount/word.txt /tmp/wordcount/out .........INFO ceph.CephFileSystem:........... ... ..........WARN Snappy.Load Dnappy: Snappy native library not loaded. .... INFO:map 0% reduce 0% and Nothing was print on! I wait for it more then 10 Minute and the word.txt content less the 10 words. by the way, the jps restut is: #jps 2913 secondaryNameNode 17888 TaskTracker 4581 JPS 2974 JobTracker and my hadoop conf is core-site.xml hadoop.tmp.dir = /usr/hadoop/tmp fs.ceph.impl =org.apache.hadoop.fs.ceph.CephFileSystem fs.default.name = ceph://192.168.58.129/ ceph.conf.file = /etc/ceph/ceph.conf mapres-site.xml mapred.job.tracket=http://192.168.58.132:9001 ndfs-site.xml dfs.replication=1 thanks peng | ||
