Hi Eli,

It is further information.

When I executed "ls -ltr /mnt/hdfs" several times in Term B,

It became the following different result in Term A:

unique: 3, opcode: GETXATTR (22), nodeid: 1, insize: 72
   unique: 3, error: -38 (Function not implemented), outsize: 16

It would be greatly appreciated if this information is useful for your analysis.

Best regards,
Tadashi
