Subject Some Questions about Node Manager Memory Used
Date Tue, 24 Jan 2017 09:04:21 GMT
My Hive job gets stuck when submitted to the cluster. To view the Resource
Manager web UI,
I found the metrics [mem used] have reached approximately the upper limit.
but when I login into the host, the OS shows memory used is only 13GB by
run command 'free', and about 46GB were occupied by cache.


so I wonder why there is such inconsistency and how to understand this
any explanations would be appreciated.
