[Kosmosfs-users] Fw: Hadoop KFS problem

[Jun R. <ju...@al...>]

Yes, this is on Linux.

Initially libkfs_access.so can't be loaded even though the LD_LIBRARY_PATH
was set properly. I have to set java.library.path explicitly to make it
work.

impl20:20000 is the meta server.

It seems that the meta server received the connection request, but for some
reasons couldn't process it properly.
