Subject Fwd: Error deploying LLAP using Apache Slider
Date Mon, 29 May 2017 19:56:29 GMT
Hi everyone,

I'm trying to deploy LLAP using Slider but the containers fail to start
due to this error:

Exception in thread "main" java.lang.NoClassDefFoundError:
Caused by: java.lang.ClassNotFoundException:
     at java.lang.ClassLoader.loadClass(
     at sun.misc.Launcher$AppClassLoader.loadClass(
     at java.lang.ClassLoader.loadClass(
     ... 1 more

Apparently I'm missing all the Hadoop libraries which are on the machine
from which I ran the hive --service llap command, but they are not
included in the Slider package. They are only included in the container
of the AM.

I found the issue HIVE-14041 which removes from the CLASSPATH in the HADOOP libraries from the machine, as they should
be shipped from the Slider client, however, in my case they are not. If
I revert back the modification everything works.

I'm following this guide
and all the env variables (HADOOP_HOME, HADOOP_CLASSPATH,
HADOOP_CONF_DIR, HIVE_HOME) are set correctly and Hive (without LLAP)
works perfectly.

Does anyone have any ideas on what I'm doing wrong?

Thanks for your help,


Fabio Buso
