So I'm trying to to get started with Accumulo. I installed Hadoop and it runs w/o problems but when I try to start Zookeeper I get:
JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
-n Starting zookeeper ...
/opt/zookeeper/bin/zkServer.sh: line 103: /tmp/zookeeper/zookeeper_server.pid: No such file or directory
FAILED TO WRITE PID
I've looked around can't seem to find an answer.
I have had the same problem. In my case was useful to start Zookeeper and directly specify a configuration file:
/bin/zkServer.sh start conf/zoo.conf
I have never heard of zookeeper, but it could be a permissions issue trying to write the file zookeeper_server.pid or perhaps the directory /tmp/zookeeper/ doesn't exist and the shell script isn't accounting for that possibility. Check the permissions and existence of those directories.
