start tsdb problem

[boastcao]

When I run the following command:
./build/tsdb tsd --port=4242 --staticroot=build/staticroot --cachedir="/tmp/tsdtmp" --zkquorum ubuntu23

The follow errors appeared:

I searched on internet,but I dont find any solutions.

Is there anybody met this problem?

Try setting --zkbasedir as well, see if that helps.

I run the following command:
./build/tsdb tsd --port=4242 --staticroot=build/staticroot --cachedir="/tmp/tsdtmp" --zkquorum ubuntu23 --zkbasedir='/home/hadoop/zookeeper'
But the problem remains.

According to a Google search for "The znode for the -ROOT- region doesn't exist!"
The top result:
https://groups.google.com/forum/#!topic/opentsdb/MwbFypTV7DA
suggests that Hbase may not be started...?

[looztra]

which version of HBase and OpenTSDB are you running?

Hbase has started.
Hbase version is :hbase-0.96.0-hadoop2.
OpenTSDB version is OpenTSDB 2.0.0 RC 2.
Is Hbase version should be 0.94?

[1tylermitchell]

Or, as I found out the hard way, you also get the error if opentsdb is not pointed to properly with the --zk... parameters.

Could you give me your hbase-site.xml and your tsdb build command?
Thank you!

[boastcao]

I check on zookeeper client:
[zk: 10.45.33.23(CONNECTED) 1] ls /hbase
[meta-region-server, backup-masters, table, draining, region-in-transition, table-lock, running, master, namespace, hbaseid, online-snapshot, replication, splitWAL, recovering-regions, rs]

There is no root-reion-server dir.
Is anyone know why?

If you're using HBase .96, use the "next" branch of the GIT repo. It includes asyncbase 1.5 with .96 compatibility. RC2 is only compatible with .94 and earlier.

[manolama]

Closing this one. For further connection issues, try the mailing list at https://groups.google.com/forum/#!forum/opentsdb

[wkshare]

we used .98 T_T

For anyone finding this thread I'll leave a note: On my system, I had to use

/opt/opentsdb/build/tsdb tsd --zkbasedir=/hbase-unsecure

[edi-bice]

I'm using Hortonworks HDP and had to change OpentTSDB config to also point to /hbase-unsecure

[typify]

This is the first (and one of the only relevant) hit in Google. I had the same issue when installing opentsdb and couldn't get to the solution. In the end it appeared a matter of getting everything right. If you think you find something, change it and it doesn't work then try another thing. Because of changing all those variables you just need to find the right mix by accident or think clearly for a moment. My issues:

• I had a stand alone zookeeper. According to the documentation you need to set export HBASE_MANAGES_ZK=false in hbase-env.sh. That is not all though, you also need to add the hbase.cluster.distributed in your hbase-site.xml and set it to 'true'.
• Make sure zookeeper, hadoop and hbase are running in that order.
• Create (if not exists) a /hbase folder in zookeeper (login using bin/zkCli.sh and type 'create /hbase'.
• Set your zk_basedir to /hbase in opentsdb.conf. In my case, make sure you use the right configuration file (/etc/opentsdb/opentsdb.conf in Debian installation)
• You may also add the --zkbasedir=/hbase parameter when starting tsdb.
• Create the tables necessary for opentsdb by starting /opt/opentsdb/src/create_tables.sh
• Finally, make sure you run all the necessary startup scripts, but do so using bash, not sh. So really run just ./build/tsdb and not 'sh build/tsdb'.

I had the same issue. The workaround for me is to set tsd.storage.hbase.zk_basedir = /hbase-unsecure in the opentsdb.conf then it works

[devsathish]

I had similar issues with Horton Works Setup (Ambari manage HBase).
Follwing setting in /etc/opentsdb/opentsdb.conf solved.
tsd.storage.hbase.zk_basedir = /mnt/hbase-unsecure

Here is the error message I was getting:
ERROR [HBaseClient.processResult] - The znode for the -ROOT- region doesn't exist!

It meant, opentsdb is unable to use zookeeper.

Works for me on hdp 2.6.2
