OpenTSDB startup error -> Caused by: java.lang.NoSuchMethodError: org.jboss.netty.util.HashedWheelTimer.(Ljava/util/concurrent/ThreadFactory;Lorg/jboss/netty/util/ThreadNameDeterminer;JLjava/util/concurrent/TimeUnit;I)V

[#1]

Hi - i've OpenTSDB v2.2.1 installed on HDP 2.4 , and i'm getting the following error on start up :

I've tried unistalling & re-installing OpenTSDB, but the error persists.

Any ideas ?

The above seems to indicate version mismatch of netty between OpenTSDB and HDP 2.4

Can you get the version of netty for OpenTSDB 2.2.1 ?

Thanks

[#3]

Here is HDP 2.4's dependency:

[INFO] org.apache.hbase:hbase-it:jar:1.1.2

...

[INFO] +- org.jboss.netty:netty:jar:3.2.4.Final:compile

[#4]

@Ted Yu -

Here is the netty version bundles with opentsdb ->

Any ideas ?

[root@sandbox opentsdb-2.2.1]# cd third_party/netty/ [root@sandbox netty]# ls -lrt total 1288 -rw-rw-r-- 1 1000 1000 33 2016-05-02 19:02 netty-3.9.4.Final.jar.md5 -rw-rw-r-- 1 1000 1000 1908 2016-05-02 19:02 include.mk -rw-rw-r-- 1 1000 1000 1310154 2016-10-08 18:55 netty-3.9.4.Final.jar

[#5]

As you can see, there are two netty jars on the classpath with different version.

I am not aware of plan to support OpenTSDB.

See if you can build OpenTSDB with the netty version hbase uses.

Shading is another option but I am not expert there.

[#6]

@Ted Yu - which two jars are you talking about ?

OpenTSDB only has Netty 3.2.4 jar.

Pls. confirm.

[#7]

bq. OpenTSDB only has Netty 3.2.4 jar

But the list below showed netty-3.9.4.Final.jar

[#8]

Maybe i'm missing the point here ..

what i meant was, The netty jars in OpenTSDB (v2.2.1) is

-> netty-3.9.4.Final.jar

is there a different version for Netty required ?

[#9]

@Ted Yu - pls see my comments above.

[#10]

bq. is there a different version for Netty required ?

As I said above, HDP 2.4 came with 3.2.4.Final which is different from 3.9.4.Final (opentsdb built with)
