Akira AJISAKA updated HADOOP-10462:
-----------------------------------
Description:
{{DF#getFileSystem}} returns null if {{DF#getMount}} is not called before. This
is because {{DF#getFileSystem}} is not parsing the df command output.
This causes {{NameNodeResourceChecker}} to print the log as follows if the
available space on the volume used for saving fsimage is less than the
specified value (100MB by default).
{code}
Space available on volume 'null' is 92274688, which is below the configured
reserved amount 104857600
{code}
was:
If the available space on the volume used for saving fsimage is less than 100MB
(default), NameNodeResourceChecker prints the log as follows:
{code}
Space available on volume 'null' is 92274688, which is below the configured
reserved amount 104857600
{code}
It should print an appropriate mount point instead of null.
