Hi Girish,

First of all this is a benign warning, it does not impact Hadoop / Metron functionality at all. You should not bother too much about it. It can be solved however if you edit HADOOP_OPTS this way:

export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=$HADOOP_HOME/lib/native"

Re: Metron profiler client unbale to load native hadoop library

Thank you Jasper,

I have set it like this in command-line:

export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=/usr/hdp/current/hadoop-client/lib/native"

And then I ran:

/usr/metron/0.4.1/bin/stellar -z krishna-3:2181

but still received same warn. Can you please advise?
