Subject [jira] [Created] (CASSANDRA-5150) sstable2json doesn't check SIGPIPE
Date Fri, 11 Jan 2013 18:58:12 GMT
Will Oberman created CASSANDRA-5150:
---------------------------------------

             Summary: sstable2json doesn't check SIGPIPE
                 Key: CASSANDRA-5150
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5150
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
            Reporter: Will Oberman
            Priority: Minor


I believe this explains the issue better than I can: http://stackoverflow.com/questions/11695500/how-do-i-get-java-to-exit-when-piped-to-head.

Basically, I expected that if I did: "sstable2json SSTABLE | other-process", and other-process
had issues and/or died then the sstable2json process would die.  It doesn't.  

My workaround is using mkfifo FILE, and having sstable2json write to FILE, other-process read
from FILE, and a 3rd overall process make sure the other two processes are working.  But,
it would be _much_ simplier if sstable2json failed on SIGPIPE.

I looks like the fix is to periodically check System.out.checkError() in the Java.
