I have a compiled jar for Hadoop including this library:
com.google.guava:guava:jar:15.0:compile
When I submit it into my Hadoop CDH5.0.1 cluster I have this error:
java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch;

The main thing is that Hadoop has an older version of guava into its classpath, loads it before mine and crashes because the used function doesn't exist.
I've tried configuration parameters such as mapreduce.task.classpath.user.precedence, mapreduce.task.classpath.first or mapreduce.job.user.classpath.first but none of them worked.
Any guess for solving this problem?

It's my first time using hadoop and try to run gridmix2 with it. I had installed hadoop 2.2.0 but when I try to generate data with gridmix i had the following error:

But in my file hadoop-env.sh i found that:
**
# Extra Java CLASSPATH elements. Automatically insert capacity-scheduler.
for f in $HADOOP_HOME/contrib/capacity-scheduler/*.jar; do
if [ "$HADOOP_CLASSPATH" ]; then
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f
else
export HADOOP_CLASSPATH=$f
fi
done
**
and the problem is that the contrib/capacity-scheduler doesn't exist in my system.
Thanks for your help!
I am trying to execute data import from Teradata to Hive using TDCH 0.15. The import is working fine while issuing a CLI command on namenode but failing with below error when integrated with oozie (using Java node). Is it because of missing library?

After this error, the deploy go fine.
But if I modify a static file (jsp for example) jrebel works fine...if I modify a java class, jrebel not works.
I don't know if is a problem relative to the error shown in console at deploy time.
In the past I userd Jrebel with eclipse with servlet (not spring) and it worked fine.
I use:
- IntellijIDEA 2016.1.1
- Java 1.8
- Spring 4.2.5
Can you help me???
Thanks
What version of tomcat are you using? 9.0.0 milestone? Grab JRebel 6.4.2 release from here and install the zip using the same instructions as for installing the nightly build at here, should fix the error.
I notice that HDFS delete commands will randomly fail. For example, in a MapReduce job I delete a directory at startup. Occasionally it fails with the error below, but will succeed on the second try.
