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
theterminal。
[] #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
