Hi!
Does anyone succesfully configure hbase to use ceph? I'm having some problems
with it, maybe anyone can help.
I have ceph already running and ceph-hadoop bindings installed ('hadoop fs -ls
/' working). I'm trying Hbase in pseudo distributed mode, but when starting
hbase-master I'm getting this error
2015-12-27 16:41:53,962 INFO [main] mob.MobFileCache: MobFileCache is
initialized, and the cache size is 1000

</property>
</configuration>
I already tried adding here fs.defaultFS, ceph.conf.file, ceph.auth.id,
ceph.auth.keyfile, fs.ceph.impl and fs.AbstractFileSystem.ceph.impl in
hbase-site.xml just in case (although i think they aren't needed here) but I
got the same exception.
I suppose from the exception I have some permission error with ceph fs but I'm
not sure.
Hope you can help me finding the right direction to fix this:)
Thanks in advance,
