Trying to start accumulo in pseudo-distributed mode on an EC2 instance.
Specs:
Ubuntu 14.04
Hadoop 2.6.0
Zookeeper 3.4.6
Accumulo 1.7.0
I just did:
start-dfs.sh (HDFS)
zkServer.sh9 start (Zookeeper)
start-all.sh (Accumulo, already did init once)
All the Accumulo processes are there because 'jps' says:
3338 Main
1374 NameNode
3491 Main
3625 Main
1858 QuorumPeerMain
1541 DataNode
4480 Jps
1741 SecondaryNameNode
3245 Main
3562 Main
So everything seems fine. However, when I check the logs I see this:
[master.Master] ERROR: localhost:9997 reports assignment failed for tablet
+r<<
and more precisely:
[tserver.TabletServer] WARN : exception trying to assign tablet +r<<
hdfs://localhost:9000/accumulo/tables/+r/root_tablet
java.lang.NullPointerException

org.apache.accumulo.server.tablets.TabletTime.getInstance(TabletTime.java:60)

Why is this NPE there?
Moreover another issue I have, probably not related is that I can't access
the HTTP monitor service from my browser (Safari) on my lap. When I put
http://EC2-instance-publicIP:50095
into the browser it says:
can’t open the page IP:50095 because the server where this page is located
isn’t responding
even though I did:
(a) set ACCUMULO_MONITOR_BIND_ALL to true in accumulo-env.sh
(b) allow incoming TCP connections to EC2 instance on port 50095
and the monitor is running and listening on 50095.
Maybe this is still a problem between my lap and EC2.
For answers, let me know which configuration excerpts I can give you.
