Paulo Motta updated CASSANDRA-16027: ------------------------------------ Bug Category: Parent values: Packaging(13660)Level 1 values: All(13663) Complexity: Low Hanging Fruit Component/s: Packaging Discovered By: User Report Severity: Low Status: Open (was: Triage Needed) > bin/cassandra may fail to execute in certain environments due to unhandled > output pipe > -------------------------------------------------------------------------------------- > > Key: CASSANDRA-16027 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16027 > Project: Cassandra > Issue Type: Bug > Components: Packaging > Reporter: Christopher Bradford > Priority: Normal > > While developing Docker images for C* 3.11.6 I noticed bin/cassandra failed > to start when executed with nohup in a container based Red Hat Universal Base > Image on Kubernetes. Curiously this issue could not be reproduced when simply > running the container on Docker. Instead it had to be scheduled within a k8s > pod. > > Running an strace indicates the following: > {code:java} > [pid 3666026] write(2, "OpenJDK 64-Bit Server VM warning: ", 34) = -1 EPIPE > (Broken pipe) {code} > > The issue occurs before the system.log file is created. After further digging > in to the command being run it was determined the bin/cassandra file was not > redirecting all output pipes. In this particular environment this leads to > the process going defunct and no Cassandra running. > > The 4 lines starting with > {code:java} > exec $NUMACTL {code} > are not handling one of the outputs (stderr or stdout). As a workaround > suffixing each line with > {code:java} > > /var/log/cassandra/stdout.log 2> /var/log/cassandra/stderr.log > {code} > {{resolves the issue and Cassandra starts without any issues.}} > > {{Rather than bake this into our containers the fix should make its way > upstream.}} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
