Xintong Song edited comment on FLINK-15488 at 1/7/20 3:13 AM: -------------------------------------------------------------- Thanks for reporting this issue, [~dwysakowicz]. This is indeed a design defect. I think the simplest solution might be {{BashJavaUtils}} output the result with a specific key or pattern, so that {{taskmanager.sh} can find result among other potential outputs. Or we can write the results into a temporal file. This is safer but a bit more complicate. We need to have unique per-TM file paths to avoid potential conflicts between multiple TMs, and also handle the file clean-ups I think the first approach might be good enough. WDYT?

The same problem (probably) occurs when using > slf4j that logs into the console. > The problem is that when calculating memory configuration with > {{BashJavaUtils}} class the result is returned through standard output. If > something is logged into the console it may result in undefined behavior such > as e.g. > {code} > Error: Could not find or load main class 13:51:23.961 > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
