Varun Saxena commented on YARN-4224:
------------------------------------
IIUC, for PUT is the proposal to get UID first and then query again with this
UID ?
So we will have have a uid endpoint and then form the UID(as a delimited
string) at server side.
In what cases would we need a PUT from UI ?
Anyways from the GET side which is our immediate use case, if I understand, we
will get a set of flows and send UID in the same response for later queries ?
So I will have endpoints like {{flowrun/flowrun_UID}},
{{entities/entities_UID}},etc.
If we have all the info, cluster, user, flow, etc. can't we create a URL of the
form {{/cluster_id/fuser/flow_name}} ? Are there any issues in Ember in
creating such a URL ? Trying to understand why a flat URL structure is
necessary for Ember.
If I am not wrong we create the REST URL in JSONAPIAdapter in ember related
code. Although I faced some issues in linking two pages when I worked on it(not
sure if this had to do something with this), but anyways queries were being
invoked with a hierarchical URL format(atleast 2 levels).
Even if UID is required what should be the delimiter ? What if flow name has
the same delimiter for instance. We need to handle it then.
If we need this format for UI, should we have this REST endpoint in addition to
our current REST endpoints(based on proposals above) for normal flow from
clients ?
