> After HDFS-6763, the quota on the standby namenode is not being updated until
> it transitions to active. This causes the jmx and the web ui files and dir
> count to be uninitialized or unupdated. In some cases it shows a negative
> number.
> It is because the legacy way of getting the inode count, which existed since
> before the creation of inode table. It relies on the root inode's quota being
> properly updated. We can make it simply return the size of the inode table.
