Yu Li commented on FLINK-11888: ------------------------------- [~sunjincheng121] has located the root cause of the port conflict issue in FLINK-11892 and will contain the change required there in the document refinement. > Refine document of how to run end-to-end tests > ---------------------------------------------- > > Key: FLINK-11888 > URL: https://issues.apache.org/jira/browse/FLINK-11888 > Project: Flink > Issue Type: Improvement > Components: Documentation, Tests > Reporter: Yu Li > Assignee: Yu Li > Priority: Major > > End-to-end tests are included in the scope of verifying a Flink release from > [document|https://cwiki.apache.org/confluence/display/FLINK/Verifying+a+Flink+Release], > and following the [read > me|https://github.com/apache/flink/tree/master/flink-end-to-end-tests] on > github to verify the nightly tests, I found several things need to be > clarified, especially on a clean environment (never run nightly tests > before), including: > * We should clarify where to find the "<flink dir>" to run the tests against > * We should clarify what preparation required before run the "Kerberized YARN > on Docker test", if user choose to. > Besides, I've observed some test failure caused by port occupation like below > (probably due to resource release failure of completed tests) but it seems to > be environment-related (checked against 4 macbook, 3 with stable failure and > 1 success; checked against 2 linux vm, 1 with stable failure and 1 success). > Will dig more and add to the document if any environment cleanup/set > required, or open another JIRA if any improvement needed for the scripts. > {noformat} > java.net.BindException: Could not start actor system on any port in port > range 6123 > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
