I'm trying to compile from branch ceph/hadoop-common/branch-1.0/, so I can do some testing with hadoop utilizing ceph. I have libcephfs-java installed from the main ceph PPA, and it is version 0.56.2. When CephTalker.java tries to compile, I get the following error:
CephTalker.java:219: cannot find symbol
symbol : method get_stripe_unit_granularity()
location: class com.ceph.fs.CephMount
return mount.get_stripe_unit_granularity();
^
Note: CephFileSystem.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 error
I checked libcephfs-0.56.2.jar, and I do not see this method:
# javap -classpath /usr/share/java/libcephfs-0.56.2.jar com.ceph.fs.CephMount |grep get
public java.lang.String conf_get(java.lang.String);
public java.lang.String getcwd();
public long getxattr(java.lang.String, java.lang.String, byte[]) throws java.io.FileNotFoundException;
public long lgetxattr(java.lang.String, java.lang.String, byte[]) throws java.io.FileNotFoundException;
public int get_file_stripe_unit(int);
public int get_file_replication(int);
Does anyone know how I might work around this problem? Do I need to use a different library or something? Am I doing something wrong?
