Re: Impala not able to start

Hi,

Can you please:

1. go to /opt/cloudera/parcels/CDH/lib/impala
2. run command:
find . -name hadoop-mapreduce-client-common*.jar

I am expecting to return:
./lib/hadoop-mapreduce-client-common.jar

3. then run:
jar -tf ./lib/hadoop-mapreduce-client-common.jar | grep MRVersion

What's the output?
