aplee commented on HDFS-9477:
-----------------------------
Thanks for your reply.
Which file do you mean by opening the file? /.reserved/.inodes/2346114?
I mounted HDFS on linux using nfs gateway, and then shared it with samba. So we
can open the files in HDFS without downloading it on windows.
About thirty records of OP_TIMES of /.reserved/.inodes/xxxx occurs in edits in
about a week after that.I think that may be related.
I know little about the file descriptor-ish feature, and will learn something
about it
