Hyukjin Kwon created SPARK-18842: ------------------------------------ Summary: De-duplicate paths in classpaths in processes for local-cluster mode to work around the length limitation on Windows Key: SPARK-18842 URL: https://issues.apache.org/jira/browse/SPARK-18842 Project: Spark Issue Type: Sub-task Components: Spark Core, Tests Reporter: Hyukjin Kwon Priority: Minor
Currently, some tests are being failed and hanging on Windows due to this problem. For the reason in SPARK-18718, some tests using {{local-cluster}} mode were disabled on Windows due to the length limitation by paths given to classpaths. The limitation seems roughly 32K (see https://blogs.msdn.microsoft.com/oldnewthing/20031210-00/?p=41553/ and https://support.thoughtworks.com/hc/en-us/articles/213248526-Getting-around-maximum-command-line-length-is-32767-characters-on-Windows) but executors were being launched with the command such as https://gist.github.com/HyukjinKwon/5bc81061c250d4af5a180869b59d42ea in (only) tests. This length is roughly 40K due to the class paths. However, it seems there are duplicates more than half. So, if we de-duplicate this paths, it is reduced to roughly 20K. Maybe, we should consider as some more paths are added in the future but it seems better than disabling all the tests for now with minimised changes. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
