I spun up a new VirtualBox VM and installed ES 5.0 from yum and when I try to start it I get an error stating:
"OpenJDK Server VM Warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using XX:ParallelGCThreads=N
The service then appears to start after the warning but when I enter "service elasticsearch status" to see if it is actually running, I see "elasticsearch dead but subsys locked". I then removed the lock(?) file located at /var/lock/subsys/elasticsearch , stopped the service and restarted it and now see "elasticsearch dead but pid file exists".
After all that, I checked the elasticsearch.log and see an error stating "node validation exception bootstrap checks failed max number of threads  for user [elasticsearch] likely too low, increase to at least ".
How do I fix these issues? I did increase the size of RAM on my VM to 3GB thinking it might be a memory issue but that did not help. Any help that anyone might be able to provide would be appreciated. Thanks.
