Till Rohrmann commented on FLINK-13938: --------------------------------------- How does this issue relate to FLINK-14964 and vice versa? They sound quite similar. > Use pre-uploaded flink binary to accelerate flink submission > ------------------------------------------------------------ > > Key: FLINK-13938 > URL: https://issues.apache.org/jira/browse/FLINK-13938 > Project: Flink > Issue Type: New Feature > Components: Deployment / YARN > Reporter: Yang Wang > Assignee: Yang Wang > Priority: Major > Labels: pull-request-available > Time Spent: 0.5h > Remaining Estimate: 0h > > Currently, every time we start a flink cluster, flink lib jars need to be > uploaded to hdfs and then register Yarn local resource so that it could be > downloaded to jobmanager and all taskmanager container. I think we could have > two optimizations. > # Use pre-uploaded flink binary to avoid uploading of flink system jars > # Use the yarn public cache to eliminate the unnecessary jars downloading > and make launching container faster. The public cache could be shared by > different applications. > > By default, the LocalResourceVisibility is APPLICATION, so they will be > downloaded only once and shared for all taskmanager containers of a same > application in the same node. However, different applications will have to > download all jars every time, including the flink-dist.jar. We could use the > yarn public cache to eliminate the unnecessary jars downloading and make > launching container faster. > > How to use the shared lib feature? > # Upload a copy of flink release binary to hdfs. > # Use the -ypl argument to specify the shared lib > {code:java} > ./bin/flink run -d -m yarn-cluster -p 20 -ypl > hdfs://hdpdev/flink/release/flink-1.9.0 > examples/streaming/WindowJoin.jar{code} > > -ypl, --yarnpreUpload <path> Upload a copy of flink binary beforehand > and specify the > path to use public > visibility feature > of YARN NodeManager > localizing > resources. -- This message was sent by Atlassian Jira (v8.3.4#803005)
