Sahana Kalakonda commented on YARN-11557:
-----------------------------------------
The Hadoop community decided to have metrics per partition and decided upon the
design to be done in phases:
# In the first phase, the get metrics was just reflecting the no label case or
only for default partition.
* YARN-6467 and YARN-9596 are the JIRAs related to the first part of the
implementation of having metrics per partition which will get the metrics only
for {*}default partition{*}.
# Second and final phase was to implement the per-label metrics work.
* YARN-6492 is the JIRA related to the 2nd part of the implementation of
having metrics per partition which generates queue metrics for each partition.
YARN-6492 fixed only the changes done by YARN-6467 but not YARN-9596.
YARN-9596 changed *getMaxAvailableResourceToQueue* (This function was iterating
through all the node labels of the queue and add all the labels resource and
returns total available resource for the queue) function in CSQueueUtils.java
class to *getMaxAvailableResourceToQueuePartition* (This function does not
iterate through all the labels and gets the available resources only for a
given partition) function. The change was to get the maximum available
resources for a partition instead of queue so this is might be the reason 'yarn
top' command gets information only for default partition.
> 'yarn top' command only shows information of default partition.
