So this indicates that the node on which the spark job is running doesn't have a hbase-site.xml to direct the job to use the hbase.zookeeper.quorum.   So make sure you have a Hbase Gateway role deployed on the node from where you are running the spark job and also try running the job if spark-submit using for eg "--files /etc/spark/conf/yarn-conf/hbase-site.xml" ...

Hi @lysConsulting The No route to host indicates that there is a network issue between this client and the HDFS cluster. I would suggest to check if the basic networking is working fine between these hosts.  ... View more

HI @Felix-Han Based on the Error, it seems there are too many request coming to that specific Region server thereby consuming the handlers it has.   So may want to check if multiple clients are hitting the same Region server ( hotspot) or try to raise the handler count.   https://my.cloudera.com/knowledge/CallQueueTooBigException--Call-queue-is-full-on-000060020-too?id=73901 ...
