Thank you!
What might be going on with the state transition of the master? Looks like the tservers can’t talk to the master without the thrift interface. Is there another interface I can enable on the master?

Yes, you should expect Accumulo to work with OpenJDK. While we don't prescribe a JDK for users, most of the developers have an interest in ensuring at least OpenJDK and Oracle JDK work well. A few people care about IBM JDK also, and we accept contributions to fix issues relevant to IBM JDK. Personally, I use OpenJDK 8 exclusively, and haven't seen this issue.

It seems like because it never transitions from HAVE_LOCK to NORMAL, it never gets around to start the thrift server. Changing back to Oracle JRE didn’t make a difference. Here’s what I get in the logs for the master: 2016-12-01 17:01:07,970 [trace.DistributedTrace] INFO : SpanReceiver org.apache.accumulo.tracer.ZooTraceCli ent was loaded successfully. 2016-12-01 17:01:07,971 [master.Master] INFO : trying to get master lock 2016-12-01 17:01:07,987 [master.EventCoordinator] INFO : State changed from INITIAL to HAVE_LOCK 2016-12-01 17:01:08,038 [master.Master] INFO : New servers: [instance-accumulo:9997[258ac79197e000d]] On the successful install it transitions right away to NORMAL and goes on the listen on port 9999: 2015-06-07 17:50:35,393 [master.Master] INFO : trying to get master lock 2015-06-07 17:50:35,408 [master.EventCoordinator] INFO : State changed from INITIAL to HAVE_LOCK 2015-06-07 17:50:35,432 [master.EventCoordinator] INFO : State changed from HAVE_LOCK to NORMAL 2015-06-07 17:50:35,524 [balancer.TableLoadBalancer] INFO : Loaded class org.apache.accumulo.server.master.balancer.DefaultLoadBalancer for table !0 2015-06-07 17:50:35,631 [master.Master] INFO : Setting master lock data to 127.0.0.1:9999 <https://urldefense.proofpoint.com/v2/url?u=http-3A__127.0.0.1-3A9999&d=DQMFaQ&c=31nHN1tvZeuWBT6LwDN4Ngk1qezfsYHyolgGeY2ZhlU&r=yH4vdeYURv2hJ1Gmntk0uc08nV-pgsJRlR6tfCR4KBw&m=PGaErZqBG4ZLhvBF_e2erg7tdil5yjEujZQMiKmp5Uk&s=TagTSNKkbvhsYiu5geGRtorEBK2ghw6Y8KvzKV2OWdE&e=> I found ACCUMULO-4513 <https://urldefense.proofpoint.com/v2/url?u=https-3A__issues.apache.org_jira_browse_ACCUMULO-2D4513&d=DQMFaQ&c=31nHN1tvZeuWBT6LwDN4Ngk1qezfsYHyolgGeY2ZhlU&r=yH4vdeYURv2hJ1Gmntk0uc08nV-pgsJRlR6tfCR4KBw&m=PGaErZqBG4ZLhvBF_e2erg7tdil5yjEujZQMiKmp5Uk&s=SNeP9F29b0ONCVeuddUvGx0xdd8Z3TLD-OxqjZsHa_s&e=> , but it doesn’t seem relevant as I didn’t try to stop. Any ideas as to what is going on? HDFS seems fine based on my limited tests with openjdk 1.8. I did find some old posts about Accumulo issues with IBM JDK. Should I expect Accumulo to work with openjdk? Thank you, Jayesh
