Shaun Kalley commented on CASSANDRA-7254: ----------------------------------------- The 'grep -q' command in the patch is not Solaris 10 compatible. The common solution, I believe, is to direct the output of the grep command to /dev/null. > NPE on startup if another Cassandra instance is already running > --------------------------------------------------------------- > > Key: CASSANDRA-7254 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7254 > Project: Cassandra > Issue Type: Bug > Components: Core > Reporter: Tyler Hobbs > Assignee: Brandon Williams > Priority: Minor > Fix For: 2.0.10, 2.1 rc3 > > Attachments: 7254.txt > > > After CASSANDRA-7087, if you try to start cassandra while another instance is > already running, you'll see something like this: > {noformat} > $ bin/cassandra -f > Error: Exception thrown by the agent : java.lang.NullPointerException > {noformat} > This is probably a JVM bug, but we should confirm that, open a JVM ticket, > and see if we can give a more useful error message on the C* side. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
