We're using plain vanilla version of apex in our environment ( no datatorrent or dtgateway ). We're using STRAM API to access the application details. We are able to find the STRAM endpoints from YARN application API.
http://<RM>:8088/ws/v1/cluster/apps?state=RUNNING The tracking URL property points to STRAM service but it's exposed by YARN web proxy. i.e. http://<RM>:8088/proxy/application_1505865155823_0039/ws/v2/stram/ http:// <RM>:8088/proxy/application_1505865155823_0039/ws/v2/stram/logicalPlan http:// <RM>:8088/proxy/application_1505865155823_0039/ws/v2/stram/physicalPlan http://<RM>:8088/proxy/application_1505865155823_0039/ws/v2/stram/loggers It works for monitoring but the limitation here though is that it only allows users to submit "GET" type requests on STRAM api. So it doesn't allow to run POST API i.e. to change log level. How to find direct application master tracking URL ( no proxy ) ? Is there a YARN api / STRAM api to do so ? So far I have found a brute force way to scrap AM log to find it but I wanted to check with community experts if there is a better way. Thanks, Sunil Parmar
