SreeHari commented on HDFS-2704:
--------------------------------
Is a low number of fs inodes a problem for namenode ? Since namenode doesn't
create new files in the local filesystem (unlike datanode) while it is running
, will it be fine if we put nn into safe mode when system run out of inodes ?
Or are we talking about just logging a warning ?
> NameNodeResouceChecker#checkAvailableResources should check for inodes

> NameNodeResouceChecker#checkAvailableResources currently just checks for free
> space. However inodes are also a file system resource that needs to be
> available (you can run out of inodes but have free space).
